Subject: Use appropriate grid shape for each craft type

New system of registration of craft types, recording for each a display
description and the appropriate grid shape.  Recipes of a registered type
are shown in the correct grid.  Recipes of unregistered craft types are
still displayed as before, using the default 3x3 grid.
