A few minor modifications:
- Last move shown as lower-case letter.
- All warnings removed from compile, along with a few bugs.
- AI improved, a bit.
- Makefile standardized, fixed dependencies.

0.1
Some code cleanup.
Added some sanity tests that can be enabled with SANITY_TESTS defined in
Makefile CFLAGS,  but currently only one test exists in the code.  Seems to be
stable enough for now, so not many tests exist.
Documents updated.

0.2
More code consitancy work.
AI optimization - big improvement but not yet there.
