ChangeLog c4 version 0.0.1pre2
==============================

1. Proper text for "about" and "how to play".
2. Replaced "scanf" functions in text version (they proved to be a liability).
3. Last move indication for text and graphical versions.
4. Borders on dialogue boxes to improve legibility at edges.
5. Gave the graphics a good gimping. In fact, I think I might have over done
it. Hmmm, you just can't buy good taste can you?
6. Fixed button signalling/restart bug  - if user quits current game by
starting a new game, the movement button signals were not disabled leading to
multiple signal connections to same button (and weird results).
7. Extended range of levels available on graphics version. The main obstacle
to adding levels is trying to think up names for them.
