MOHAWK: RIVEN: Add Autosave Support

The game will autosave to slot 0 using the save
period given in the scummvm config file.
Or when the user quits.

Autosaves are only allowed when an autosave is
in slot 0, there is no save in slot 0, or there
is a save, but it is corrupt.

This will not override any saves the player
has previously put in save slot 0. If there
is a save in slot 0 that is not an autosave
then there will be no autosaving.
