* Fix css flipping: for Simple, it still depended on the content language (however, no css actually needs flipping there). For Standard/CologneBlue, I re-added flipping even though it's not needed there either. Just in case css is added that does need flipping, so it is future-proof :). Consequently, I added noflip to the existing css.
* For this flipping I added a parameter to addInlineStyle(), which I assume to be useful in other cases as well
* Make ResourceLoaderUserOptionsModule and ResourceLoaderUserTokensModule depend on mw.user
* Load mw.user.{tokens,options,groups} load as TYPE_COMBINED instead of TYPE_SCRIPT. The latter wouldn't wrap the code in mw.loader.implement()
** ...but make sure 'user' (user scripts) is excluded, that one needs to not be wrapped in a closure
* Make TYPE_COMBINED actually work in makeResourceLoaderLink()
* Add a comment in makeModuleResponse() to explain what the weird is_array( $scripts ) stuff is all about
* Add FIXME about how mw.user.options should split off the CSS part into a separate module
TODO: Since the alias is globally available from the start, the 'mw' argument in the wrapper is redundant, so that should be removed at some point as well.
TODO:
* Are there instances where we might want to restrict CSS as well as JS?
* Would a $wg config option and/or user preference and/or index.php GET parameter to limit inclusion be useful?
* Can we deprecate any of the existing $wg config options?
* What's going on with the duplicated code between OutputPage and SkinTemplate?
* Modified Xml::encodeJsVar() to allow it to pass through JS expressions without encoding, using a special object.
* In ResourceLoader::makeModuleResponse(), renamed $messages to $messagesBlob to make it clear that it's JSON-encoded, not an array.
* Fixed MessageBlobStore to store {} for an empty message array instead of [].
* In ResourceLoader::makeMessageSetScript(), fixed call to non-existent function mediaWiki.msg.set.
* For security, changed the calling convention of makeMessageSetScript() and makeLoaderImplementScript() to require explicit object construction of XmlJsCode() before interpreting their input as JS code.
* Documented several ResourceLoader static functions.
* In ResourceLoaderWikiModule, for readability, reduced the indenting level by flipping some if blocks and adding continue statements.
* In makeCustomLoaderScript(), allow non-numeric $version. The only caller I can find is already sending a non-numeric $version, presumably it was broken. Luckily there aren't any loader scripts in existence, I had to make one to test it.
* wfGetDb -> wfGetDB
* Added an extra line break in the startup module output, for readability.
* In ResourceLoaderStartUpModule::getModuleRegistrations(), fixed another assignment expression
* Break long lines.
* Convert long or unnecessary ternary operator usages to if/else.
* Fixed excessively clever assignment expressions.
* Rename $cache to $cacheEntry.
* Removed unnecessary web invocation guards. Their perlish form was making me uncomfortable. BTW, unlike in Perl, die() is not a function, it's a special case in the PHP grammar which very roughly simulates the Perl syntax:
die "x"; // works
0 || die("x"); // works
0 || (die); // works
0 || (die "x"); // fail!
