* Mostly whitespace in callers: $('foo').bar(baz,quux) => $( 'foo' ).bar( baz, quux )
* Also several occurrences of mixes spaces and tabs in the indention in front of a line, converted to tabs.
* And double spaces -> single spaces at random.
* Add jQuery QUnit module
* Add a return value to mw.Map.prototype.set
* Add fallback to 'body' for options.parent in a new $.messageBox
(this is a re-do of r87830, but without breaking mw.config, see r87830 CR)
