The `fmtt` formatter SVN

Add keywords to `src/` dir; add ignores to `VS2003`.

Context pattern puzzling.

Ups, GROW() was crippled ...

Update the VS 2003 project files to include the proprocessing tool `ctxgen`.

Update VS 2008 project files to include the preprocessing tool `ctxgen`.

Place digraph pattern preprocessing/sorting into external program. This simplifies the context matching stuff at runtime a lot. Context patterns are now defined in a text file, processed into C array definitions and then included into fmtt at compile-time. Is kind of working, but there is still some work to do.

... yet another silly error fixed.

Tiny typo fix.

Use SVN keyword substitution and get rid of the annoying "version.h".
Protect marked digraphs through -D processing.

Cleaning up (charnames, feature macros, ...).
Update "version.h".
