Log message (10 lines):
An email conversation with Chuck Fresno turned up several forms of
symmetry which were not implemented in Solo. Now they are.

In the process I've completely retired symmetry_limit() on the
grounds that some of the new symmetries do not have a rectangular
base region; instead I determine the base region by going through
the grid and finding every square which is not transformed into a
lexicographically lower square by any symmetry operation. This means
that adding new symmetries is now _only_ a matter of encoding the
actual transformation rules.
