Implement hitTest

Cocoa calls hitTest on our view to determine if
the view should get the mouse press. We always
said, "yes" and did all the logic ourselves. Turns
out that we can say "no" if I'm transparent to
mouse events and remove all that code where we do
all the work ourselves. Big maintenance win!

For the time being I've kept the
"transparentViewForEvent" method since it might be
useful for others, but no one is using it at the
moment and we may just kill it soon. HitTest should
handle this situation correctly.
