Lots more memory/resource leak fixes. There are still more, but this solves about 75% of them.

These fixes also speed up tex2rtf greatly.  I can now build all the RTF version of the wxWindows manual in under 30 seconds, when before it took around 90 seconds.
Curley Brace matching is turned back on again.  I cannot find any places where it does not work.  If you find one, let me know
