Subject: [PATCH] Bug 688710 - splashscreen shouldn't be always on top on OS X

Activate the "hides on deactivate" behavior for splashscreens,
torn-off menus, utility windows, tooltips and notifications: when
another application is brought to the front, these windows are hidden
so as not to obscure it. This is the expected behavior for
application-specific floating windows on OS X.
