Subject: [PATCH] Fix QToolButton size glitch after adding menu

Invalidate the cached size hint when changing the menu on a QToolButton.
This is required because the correct size may be different for a button
that has a menu versus one that does not; failure to recompute the size
may result in incorrect display if the button's sizeHint() has been
previously called.
