MOHAWK: Switch to slot based save file naming for Myst

Myst previously used the user provided description as the save filename.
This was not working when the user entered chacacters forbidden by the
filesystem.

The actual save format has not changed. Old saves are still compatible,
but must be renamed to 'myst-###.mys' and 'myst-###.mym'.

Fixes 7106.
