de6ae79959 Fixes bug 624133, "Input freezes after impossible character". Try 'shsM' in
ACIP or 'ShSm' in Extended Wylie to see the new behavior.

We use a trie to store valid input sequences.  In the future, we could use
the same trie as a replacement for the more inefficient HashSets we use to
store characters, vowels, and punctuation.  For example, we'd use
'validInputSequences.put("K", new Pair("consonant", "k"))' when reading
in the ACIP keyboard's description of the first consonant of the Tibetan
alphabet in 'TibetanKeyboard.java'.

Note that the current trie implementation is only useful for 7- or 8-bit
transcription systems, and works best for tries with low average depth, which
describes a transcription system's trie very well.  If you used arbitrary
Unicode in your keyboard, you'd need a different trie implementation.

Improved the optional keyboard input mode status messages.

a6cc4a7ff3 Removed/commented out/tagged some unused local variables.
Added a JUnit test for the new Trie that fails at present since the Trie is
case-insensitive.  Running JUnit tests is not something our build system
knows about at present, but Eclipse 2.0 makes it very easy.

Fixed a few compiler errors due to imports I'd forgotten.

5249c48807 Factored TibetanDocument into two classes, one that is a
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.

fd1b4dd468 Now breaks the line after the last whitespace, not the first.
I cleaned things up a bit, and I've made logging optional since I don't yet
trust the code fully.

A Wylie underscore at the end of a line is worth looking into further, at the
very least.

0ad135f8f1 This may well be a fix to the "Improper line wrapping" bug. The fix
is basically that we use our own special ViewFactory, with a new
subclass of LabelView (the view RTFEditorKit uses for the nitty
gritty) that is aware of Tibetan.

There are a couple of nasty hacks still here, and Swing's
documentation for doing what I did was quite poor.  I searched the web
for hours, read the Javadocs and the tutorials, and consulted a Swing
reference book, but I still don't have tremendous confidence in this
solution.  If it fundamentally doesn't work, though, we have to define
our own first-class Document, Element hierarchy, ViewFactory, Views,
and EditorKit.  So let's hope it *does* work fundamentally.

I can't say for sure if this even works, as I have yet to run this
code on a machine where Jskad works properly.  I had major trouble
installing the TMW fonts on Linux, and have yet to resolve it, even
after verifying via xlsfonts that the fonts were installed and then
changing TibetanMachineWeb.java to look for them.  Because I haven't
tested this yet, a lot of nasty code is tagged 'DLC' and commented
out.
