Com_game_f: try execing quake.rc automatically..

Not convinced there are any issues with this, and it solves these
problems:
- change to new gamedir without execing quake.rc and exit: the
  config.cfg in the new gamedir will be clobbered with the settings
  from the previous gamedir.
- discrepancy between -game command line arg and "game" command.

Video mode is locked during the "exec quake.rc" to prevent the mode
from changing.
