*: drop {gtk,qt}-recordmydesktop subdirs
This restores the recordmydesktop/ subdir as root from the mirror I cloned by fork from. I have no particular interest in the gtk/qt frontends and it doesn't appear they were part of a single tree in the past. But I will probably preserve backwards compatibility of the cli so they can continue to work with this fork installed.
