Subject: [PATCH] Prevent bottom content inset from being negative.

On an iPad with a hardware keyboard and the shortcuts bar enabled:

If the scroll view has a bounds of:

CGRectMake(0, 138, 787,  327)

and the keyboard has a bounds of:

CGRectMake(0, 713, 1024, 55)

Then the bottom inset ended up being -107, which would make the bottom content of the scroll view inaccessible.
