Allow crafting from the craft guide.

This adds some buttons that when clicked, checks to see if you
have the required materials in your inventory (using the currently
selected recipe), and moves as many items as possible from the
player's inventory to the crafting grid.

Three buttons are added: craft one ("1"), craft ten ("10"), and
craft as many as possible ("All").

The buttons are only shown for "normal" and "shapeless" recipes;
for all other recipe types the buttons are hidden.
