libsaria: Comment out most code, begin new preferences

I commented out most of the code in libsaria/__init__.py to make it
easier to clean up.  I also began work on libsaria/prefs.py for managing
preferences.

NOTE: For the next several commits, the best way to test changes is by
importing libsaria through the python interpreter.  Trying to run
ocarina will probably fail.
