Now that Map has some seriously complex deductions, it's about time it had a command-line solver. In order to do this, I've had to expose the internal region numbering because the solver has to have some way to state which region it means; and in any case it's also useful to have human-visible region numbering so that two people can discuss a puzzle they're solving together. So pressing L during play now toggles the display of region numbers; and `mapsolver' uses those same numbers when showing its working and its solutions. [originally from svn r6244]
