(un)install -> (un)register, add nogui mode for use in installer

Browse Source 
The nogui mode is required for the installer, to keep the noise low.
Also, get rid of QApplication passing, as all methods we call
are static anyway, which made the compiler complain about
unreferenced formal parameters.
