mainly made the code shorter:

Browse source 
- removed some needless if's
- replace multiple "var x" for one, comma separated declaration.
- added a local fn called now() for the (new Date)s
- fixed the indentation of a block, and a typo in a comment.
- used fn instead of prototype where possible
- jquery fx: exposed the speeds hash as jQuery.fx.speeds.

Also fixed (again) line endings
