Subject: Cocoa: calling QEventLoop::exec from mouse up causes problem
If one create e.g. a modal dialog from a mouse up event handler, we
qt_button_down global variable was pointing to a widget before the
handler returned. This meant that you could not push another button
in the window, since the qt_button_down would grab the mouse. This
patch clears qt_button_down before sending mouse up events.
