New utility 'patternpicture', to build a Pattern from an xbm. This utility works basically the same as galaxiespicture: you feed it a .xbm bitmap on standard input, and it constructs a game ID which solves to exactly that image. It will pre-fill some squares if that's necessary to resolve ambiguity, or leave the grid completely blank if it can.
