Enforce redraw of fancybox wrap

In Webkit-based browsers, if your mousecursor is exactly at the position
of the next-button while fancybox slides in, you have to click twice to
get to the next image because the first click gets eaten by Webkit to
check the :hover state of the 'a' element used for the next-button.

If we enforce a redraw by doing a hide().show(0), Webkit will reevaluate
the :hover state and the first click will trigger an click event like
expected.

Re-merging css3 transformations into branch 'master' of https://github.com/fancyapps/fancyBox
Updated css3 transitions code to use translate3d instead of changing left/top.  This relies on an updated custom jquery.transit library with support for translate3d, which should trigger hardware acceleration and improve performance.
Merge remote-tracking branch 'origin/css3-transforms'
