Handle GTK enter and leave notification events and pass them to WebKit as

mouse move events. This prevents an HTML widget from staying in the mouseover 
state when the cursor leaves the window. Add a new ui test that checks 
the specific case that was broken by warping the mouse pointer inside and 
outside the content area. 

BUG=24660
