Schach 3.2.10 release.

Fixed the post-install KeyError, and added a better-looking theme.

Schach 3.2.9 release.

Schach v3.2.9 has undo/redo, move history, 20-level engine play and random move, and limited help docs. There are a couple known bugs to fix, namely the bug that prevents the user from re-maximizing the window after it has been un-maximized. Also, the theme hasn't been improved as of this version. That will come in a later release. Please report any other bugs you find, using the Issues tab, and I will look into them.
