Simplified the easing options - we now provide "swing" and "linear" (defaulting to "swing"). This is in response to #928.

Animations now use a single interval timer, global for all animations. This severely improves the performance and responsiveness of the animations in most browsers.

Forced the test suite into standards mode. Fixed some issues with how opacity was handled in IE. Fixed a number of IE fx bugs.

Removed some un-needed code from css() and fixed a bug with how Safari handles childNodes in makeArray.

Added an initial version of the new animation test suite. (You should never see red on the suite page - an error message will be generated wherever possible.)

Clean up for revision 1462: "Fix for Safari crashes when doing DOM Manipulations" to use jQuery.makeArray

Cleaned up how event removing was handled. All expandos are now removed when they are no longer needed. Additionally, a bug where all events are unbound if an incorrect event handler is provided, was fixed.
