jquery issue with event.which in Firefox -

Trying to detect a keyboard event like keydown or keypress - like #607240: Usability: Allow AJAX behaviors to be triggered with spacebar - causes a flood of warnings in Firefox:

The 'charCode' property of a keyup event should not be used. The value is meaningless.

this seems to be a problem with jQuery - there is a fix in the comments on http://api.jquery.com/event.which/ and though he's referring to jQuery 1.4.2 it seems to work for 1.3.2 as well.

this is an adaptation of that fix as a patch. i couldn't find a jQuery bug for this but i figured other people might run into this same issue.
