v0.7

This release has fairly major bugfixes, and some relocation of code. If you're using cvs, make sure to do "cvs update -d".

UIs must be adjusted to use the setPostion(int) method instead of the integer constructor.

I have included support for graphical cards, but I have not tested it.

Also, this release is a checkpoint before some major reorganization of the ruleset code, but more on that later.
