Removal of jQuery.Browser usage

Removal of jQuery.Browser usage


Hey John,
first off, nice job with the live query / jQuery.support commits! I'm
almost /feeling/ the improvements, without even testing them :)
I'm curious about a couple lines in the commit, thought you might
explain them to us:
- ajax.js: It seems instead of a substitute, you simply removed the
safari check. What was the reason for this?
- core.js: removal of opera/display fix, color() method with safari
fix, the whole display none logic - does this mean we simply don't
support getting some style values for display:none elements? (which is
fine, just wanted to check)
Other than that, it looks all good, a lot of nice fixes / better logic
in there, especially in event.js. Thanks!
Cheers,
Paul
