Update thirdparty libraries/submodules

[marcelgerber]

Updates multiple libraries/submodules.
All unit tests still pass, extensions should still work. No breaking changes.
Hopefully helps extension developers in using the latest versions.
Fixes #9670.

jQuery 2.1.0 -> 2.1.1 (May 5, 2014):

http://blog.jquery.com/2014/05/01/jquery-1-11-1-and-2-1-1-released/

Lodash 2.2.0 -> 2.4.1 (Dec. 2, 2013):

https://github.com/lodash/lodash/wiki/Changelog#v241
New functions:

• _.constant
• _.create
• _.mapValues
• _.noop
• _.now
• _.property
• _.xor

LESS 1.7.0 -> 1.7.5 (Sep. 3, 2014):

https://github.com/less/less.js/blob/master/CHANGELOG.md#175

I didn't go with LESS 2.0.0 (released Nov. 9) as it requires some changes in Brackets (and probably in extensions as well).

RequireJS 2.1.5 (866edd0) -> 2.1.15 (latest master - Nov. 7, 2014):

requirejs/requirejs@866edd0...master

Question: why is the expanded version of jQuery included even though only the minified is referenced anywhere?

[redmunds]

@le717 The expanded version is for debugging.

[marcelgerber]

I tried to use the source map, but I couldn't get it to work (I suppose it has to do with local files - Chrome is pretty restrictive with accessing them). Therefore the non-minimized version is still included.

Perhaps it makes sense to update each library as a separate commit instead of all in one.

[marcelgerber]

Hm, you're right. It's gonna make git bisect and friends easier.
Will do this now. Should be easy.
E: Done.
