DefaultStyledDocument, and another consisting entirely of static utility
methods for processing Tibetan text. Moved TibetanDocument.DuffData
into its own class.
I think this makes things a bit more transparent, and gets us a little closer to
making clean use of Swing.
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.
Added a "Quit" option to Savant's File menu. Factored out the Close
option in doing so.
Exceptions in many action listeners are now handled by
org.thdl.util.ThdlActionListener or org.thdl.util.ThdlAbstractAction.
Many exceptions that we used to just log now optionally cause aborts.
This option is on by default for developers using 'ant savant-run'-style
targets, but it is off for users.
An erroneous CLASSPATH now causes a useful error message in almost
all situations.
Fixed some typos and bad links in Javadoc comments.
Added a simple assertion facility, but the overhead is suffered even in
release builds.
Factored out the code that sets up log files like savant.log and jskad.log.
