GlobalShortcut_win, mumble.pro: remove use of HardHook in GlobalShort…

…cut_win.

This also lets us remove MinHook from the Mumble client itself.

This code is part of the client-in-overlay feature that we had
for Windows and OS X. However, that feature is broken for Qt 5
and never had good performance.
