Sanity-checking patch from Phil Bordelon: since Solo can't cope with more than 36 distinct symbols (it runs out of alphanumerics), check this in validate_params. I hate to do this, since I like puzzle sizes to at least be open-ended in _principle_, but in this case there's a fundamental UI limitation which won't be fixed by getting a faster CPU. [originally from svn r6098]
