- prevent highlighting a clue square at all
- enable easier switching between highlight types by not requiring
a left-click highlight to be left-click-cancelled before
right-clicking, and vice versa
- fix bit-rot in -DSTANDALONE_SOLVER
Also one of mine:
- replicate Richard's -DSTANDALONE_SOLVER fix in Pattern, where it
was also broken.
