Quit should clear domain
|Reported by:||SF/madm00se||Owned by:||sev-|
If you select a game that isn't currently supported (say, an engine isn't currently compiled) and try to play it, the configuration domain is set but, naturally, the engine fails to launch and you return to the launcher.
If you now try to quit the launcher, the domain is still set and main again tries to launch the engine, fails, and returns you to the launcher. Repeat ad infinitum.
The main loop could either react to the return value of the launcher (which isn't currently used) or the launcher could clear the domain. Or both. Patch makes launcher clear the domain when quit is selected.
