Ability to make OpenMW "portable"
I am running OpenMW .351 on Windows XP SP3.
As of now, OpenMW writes to files in my user directory. It would be handy if it could be configured to read and write files only in its own directory, ie portable. This would be very helpful so I can run multiple versions of OpenMW with different mods to do some testing and debugging.
