Add utility functions and fixes for iPhone/iPad integration.
Review Request #1593 — Created May 16, 2010 and submitted
Add utility functions and fixes for iPhone/iPad integration. This adds some stuff to gravy to make apps work better on the iPhone/iPad. A new $.proxyTouchEvents function has been added, which causes touch screen events to be forwarded to existing mouse event handlers. It's intended for basic use cases where multi-touch events really don't need to be handled. $.browser has been updated with a 'mobileSafari' check, making it easier to determine whether we're running on the iPhone/iPad. A workaround for jQuery bug #6446 has been implemented, which basically fixes an issue with the result from $.offset() being incorrect. Tooltips are disabled on iPhone/Pad, as they're really not at all useful and their hover events manage to get in the way of other events.
Tested this with my Review Board change (/r/1592/).
