Merge branch 'chrome-slice-comment' of https://github.com/ajpiano/jquery into ajpiano-chrome-slice-comment

Add missing line break after copyright header and trailing semicolon at the end of the minified version.

Add another tweak for handling CSP - we need to make sure that we don't trigger any eval on load (not sure if it's the best tweak, definitely not ideal). Add a test page as well so that it's easier to catch problem.

Clarify cygwin instructions slightly and swap the order of arguments to which in Makefile because of a bug in current versions of MSYS that causes only the first argument to /bin/which to be searched.

Replace build system with a faster new one that uses Node and UglifyJS and generates smaller minified files. Also removes builds through rake/ant since having 3 different build systems was too much to maintain (make was the only one consistently kept up-to-date). Fixes #7973.

Merge in data_nocollide branch. Fixes #6968, improves unit testing framework checks for leaky stuff.

Defer scriptEval test until first use to prevent Content Security Policy inline-script violations from occuring. Fixes #7371.

Introduce a temporary hack to allow jQuery.fn.data("events") to continue to work. This will be going away in 1.6. More information will be available in the 1.5 release notes.

Add a comment to explain (and enforce the temporary-ness of) an extra line of code added to workaround a Chrome 10 bug

Put the split to get the list of promise methods out of the promise method itself and also switched from jQuery.each to a while loop to remove as much overhead as possible. Thanks go to scott_gonzalez for reminding me of this.

Implements joined jQuery.when statements. Makes it so calling jQuery.when with no parameter returns a resolved promise. Ensures promise method on promises supports the promise(obj) signature. Ensures a deferred and its promise always return the same promise (itself for the promise). Unit tests provided.

Fixed the ajax test regarding the jsonp option set to false and added a test to control the prefilter actually does not tamper with the url.

Removed internal dataTypes option and added headers & crossDomain options into commented out options of ajaxSettings.

Fixes #2994. Not finding a transport now fires the error callbacks and doesn't make ajax return false. Had to revise how jsonp and script prefilters & transports work (better separation of concerns). Also took the opportunity to revise jXHR getRequestHeader and abort methods and enabled early transport garbage collection when the request completes.
