Remove duplicated function from QCocoaEventDispatcher

The qt_mac_waitForMoreModalSessionEvents() is identical to
qt_mac_waitForMoreEvents(), except that it passes a different inMode
parameter to [NSApp nextEventMatchingMask]. Change the latter function
to take the mode as a parameter itself, defaulting to the default mode.

Change the dequeue parameter to [NSApp nextEventMatchingMask] from YES
to NO. Having the function dequeue the event, and then immediately
reposting the event is not necessary.
