Due to removal of various features in jQuery 1.8, the following changes were necessary:
jQuery.browser #9385 changed to custom function that checks specifically for keydown availability. Although this function could come in many different flavours, I wrote it to be as specific as possible for keydown based on the recommendations of Quirksmode and Resig
jQuery.data() #11718 changed to jQuery._data() when 1.8 is detected.
All tests for Bootstrap 2.1 now pass in both 1.7* and 1.8.0.
PS. I have no fucking idea why the popover.js file is showing up as a complete re-write. It's formatted the same as the others, unless the original was different than all the rest. Anyways sorry about that, I give up trying to fix it. If you know what's wrong let me know I can re-submit the pull.
