magnets: Area constraints; fix message. (The restriction on 2x2 puzzles is because the board layer-out doesn't use neutral pieces on such small boards, and the only soluble 2x2 boards have neutral pieces. I haven't investigated the Tricky size limit, but it seems entirely reasonable that all the smaller boards are too easy. --bjh21) (cherry picked from Android port, commit 133794977a13767e0c1596be6a5b26f2cf2d1fd1)
