Added a flexible mechanism for persistent boolean-, integer-, and

string-valued preferences built atop java.util.Properties.

How it works: the jvm is asked first, and then the user's prefs file, if it exists,
then the system-wide prefs file, and then the built-in preferences.  Finally, for
robustness, a default may be optionally hard-coded in the source.

I made several things configurable, too:

the default Tibetan keyboard
the default font sizes and faces
whether you want developer-only features enabled
Savant's file extension (.savant)
etc.

The only known problems are the following:

The default location for the user's preferences file is windows-specific,
arbitrary, and not in the user documentation.  Likewise for the location of the
system-wide preferences file.  You can change them using 'java -D', though.

There is no "Save preferences" option yet, and closing the program does
not save preferences either.
