cached some vars and it proved to be faster.

- 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

jquery event: from #2249, adding $.event.proxy to link event handlers, and implementing it on $.event.add, $.fn._toggle and $.fn.one.
It also fixes a bug in $.fn.one that was unbinding ALL the existing handlers.

jquery core: in $.makeArray, improved array-like detection, Safari reports nodelists as 'function', so I got back to attribute sniffing.

jQuery.event.fix performance boost. An example: click event was previously ~3ms and is now < 1ms. jQuery.event.trigger also got another small boost in performance.

jquery core: fix for #1960, delegating to document.getElementsByName for [name=...] selectors (not in combination with :not)

test runner: updated the tests for makeArray

- Adding the enhancements to the test runner, to accept multiple(and negative) filters from the GET variables, as specified in the ticket #2738.

jquery core: Patch from #2619 applied, making makeArray more flexible and faster; removed hint to ticket from (previously failing) test

Fixed regression with 5276 where return false in first handler of multiple handlers was ignored. And 5276 log message says 200% but I meant 20%.

jquery testrunner: accept regexp to select tests, eg. /test/?^core|^selector to run both core and selector module

Some small optimizations to the event module. jQuery.event.trigger over 200% faster in IE and less code. Thanks in large to Ariel Flesler.
