TM->TMW and TMW->TM conversion in RTF is now supported. I've

Browse source 
noticed that formatting is mostly OK but sometimes gets bungled slightly.
I tried everything I could think of, and now I'm passing the buck to Java's
RTF support.

TMW_RTF_TO_THDL_WYLIE (now misnamed) support TMW->TM
conversion (but not TM->TMW).  There is an automated test case for a
TMW->TM conversion.

I have full confidence in this conversion.  Even the smallest glitch in the core
functionality (not formatting) would surprise me.

Note that the JUnit test TMW_RTF_TO_THDL_WYLIETest sometimes fails
due to one- or two-line diffs between the actual and expected outputs.  This
is because Java's RTF support is not deterministic, I'm guessing, and is not
a real failure.  I'm too lazy to make a more elaborate sed/diff mechanism
that works on all platforms, and that would complicate the build anyway.
