-----------
DC: Let scummvm.ini override autodetect of games

If a game CD has a scummvm.ini file with at least one game domain in
it, the normal autodetection is now bypassed and a menu of only the
games in the .ini file is presented instead.  The descriptions of the
games are taken from the .ini file, but icons are still scanned for
in the old fashion.

Note that previously ScummVM would read global options from the
scummvm.ini file on the boot disc (if present), but now global options
are instead taken from the scummvm.ini on the game disc (in case of
a disc swap).
