4ec6b0cce1 Set up node-jscs via Grunt (and pass it)
* Set up Grunt via package.json (run `npm install` in mediawiki-core)
* Add grunt task for node-jscs (NEW)
  This is a style checker (as opposed to jshint, which is for
  code quality). There are a few small style-related things that
  JSHint can check (camelcase, onevar etc.) but those are being
  deprecated in JSHint v3, people should use more sophisticated
  tools like node-jscs for this instead. As such this commit
  removes moves of those options from our jshint configuration.
  See: http://jshint.com/blog/jshint-3-plans/
* Add grunt task for jshint
  This will use the same jshint configuration as we use on
  Jenkins but makes it easier to run locally from the command
  line by being part of the same `$ grunt test` task list.

Also:
* Changed jshintignore to use "dir/**"" instead of "/dir" or "dir"
  because the latter is not compatible with Grunt for some reason.
  See also https://github.com/gruntjs/grunt-contrib-jshint/issues/126.

Examples of coding style rules that were being violated that we
can now catch in node-jscs:
* Operator "," should stick to preceding expression
* Missing space after "if" keyword
* Multiple line break
* Empty block (in jquery.textSelection and mediawiki.language)

8d306686cf Lint: Go-go-gadget jshint! Passing entire JS code base (again).
There were still some files not passing jshint, and for files
that did, we managed to screw 'em up again.

Added more explicit settings in .jshintrc to avoid relying on a
kind of default somewhere. There are too many default-factors:
closest(.jshintrc), ~/.jshintrc, IDE/editor, node-jshint..

Added node_modules/ and extensions/ to .jshintignore.
Previously "$ jshint ." would recurse over all kinds of
unrelated code. Extensions should have their own jshint
dotfiles. When linting from Jenkins this won't be a problem as
those will be ran per repo (so when linting core it will skip extensions and when in an extension dir, the core dotfiles
don't apply as they'll be out of scope).

Some of our modules are really messy and should be refactored
to be less spaghetti-ish and have more descriptive variable
names and more manageable function-level complexity.
But for this commit, I'm keeping it as much as-is as possible,
because its hard/large enough to review as it is.

A few errors are cited below to give an impression of the kind
of warnings I addressed (for cases where the diff isn't
so obvious):

* jquery.hidpi.js: line 110, col 15, Empty block.
* mediawiki.jqueryMsg.js: line 34, col 17, Too many var statements.
* mediawiki.jqueryMsg.js: line 145, col 33, Strings must use singlequote.
* mediawiki.action.edit.js: line 74, col 73, 'selectText' is defined but never used.
* startup.js: line 19, col 22, 'isCompatible' is defined but never used.
* jquery.byteLength.test.js: line 26, col 9, Identifier 'U_00A2' is not in camel case.
* jquery.localize.test.js: line 63, col 29, 'attrs' is defined but never used.
* mediawiki.cldr.test.js: line 72, col 27, 'mw' is not defined.
* mediawiki.jscompat.test.js: line 6, col 17, Strings must use singlequote.
* mediawiki.api.parse.test.js: line 9, col 17, Strings must use singlequote.
* mediawiki.api.parse.test.js: line 7, col 15, 'mw' is not defined.
* mediawiki.api.parse.test.js: line 14, col 24, '$' is not defined.
* mediawiki.api.test.js: line 43, col 28, 'data' is defined but never used.

Other fixes:
* Add closures fix implied global errors ($, mw and more),
  and prevents local variables from becoming globals.
* Avoid jQ magic map arg etc. (per code conventions).
* Fix incorrect usage of jQuery methods (prop instead of attr,
  prop false instead of removeProp, ..).
* Unquote keys in object literals for consistency, and
  enforce single quotes (no magic quotes in javascript, as much
  as we might think "\n" and '/n' are really exactly the same).
  Chose single quotes over double quotes since that's what most
  code already had and what conventions seemed to prefer
  (both the old generic ones and the new per-lang ones since
  2011/2012).
* Enforce camelCase variable names with jshint per code
  conventions.
* $foo.on('x', fn).trigger('x') -> $foo.on('x', fn); fn()
  (No event simulation overhead, unless intended of course)
* Incorrect indentation (ignore whitespace in the diff!).
* Avoid proprietary selectors like ':first' when .eq(0)
  afterwards is just as possible (significantly faster in
  jQuery due to mostly avoiding the Sizzle engine and going
  native in modern browsers).
* When at it, convert deprecated jQuery methods to new ones.
  Mostly just .delegate(sel, type, fn) -> .on(type, sel, fn).
* Addressed whitespace here and there.

Interesting:
* mediawiki.js: local function "compare" wasn't used anymore
  (hasn't been in a while!) removed per jshint warning.

* mediawiki.special.recentchanges.js: Was a mess, only a few
  lines of code, rewritten.

Pfew, let's hope it's the last one before we lint from Jenkins!

089c58d232 jshint: resources/jquery/*
* .jshintrc: Updated to include more strict options that match
  our code conventions.
  Also separated into 3 groups:
  - stricter (curly, eqeqeq etc.)
  - laxer (smarttabs, laxbreak)
  - envrionment (browser)

* .jshintignore: Updated to include more third-party/upstream files
   that should not be linted.

* Most of it is just routine cleanup, a few notable points:

 - jquery.autoEllipsis: Removed unused variable $protectedText.

 - jquery.arrowSteps.js: Remove <!-- --> and language="javascript"
   that hasn't been needed for almost a decade.

 - jquery.byteLimit: Use dashToCamel key for .data(), this already
   happens internally in jQuery data(), since data storage should use
   keys that are usable as identifiers. The dashed versions are to
   populate these from data-attribute-names, which then becomes
   data.attributeNames. jQuery data() takes both forms as
   convenience.

 - jquery.client.js: To avoid a rewrite of it, allowing unexpected
   assignments (boss) and eval (evil) in the functions that use that.
   Left as it is for now, could use a rewrite later.

 - jquery.color.js: Tolerate unexpected assignment for now (boss).
   Left as it is for now, should perhaps be refactored later.
   Also re-ordered per jshint/jslint to put definition before
   invocation. This option can be disabled, but then it doesn't
   warn for invoking undefined functions (or typos) at all.

 - jquery.expandableField.js: Remove empty switch/case.

 - jquery.localize.js: Alias mw global.

 - jquery.suggestions.js: Use e.which; jQuery.Event normalizes
   e.keyCode etc.

 - jquery.tablesorter.js: Alias mw global.

 - jquery.textSelection.js: Fix leakage of variable in global scope
   of var "i" and "j".

 - mediawiki.util.test.js: Fixed implied global `pCustom`.

* Review with -w for your own sanity.

85d5e617d7 Removing unneeded wraps and using $ and mw instead of jQuery or mediaWiki since r79246 enabled the private scope by default. No need for two wraps.
(the wraps had an extra indention, hence the diff will probably look huge)

83a7822df7 Wrote jquery.colorUtil plugin.
* Introduces rgbToHsl and hslToRgb functions
* Introdoces a simple way to get a brigher or darker color
* Moved getRGB() function and colors-array from jquery.color to it so they are publically available.
* Applied fixed from JSLint to all of this
* Made jquery.color use these instead to avoid duplication and added dependency for it
