Proposed changes

Space and the arrow keys were bound to the whole window, so typing a space in the next seed field immediately generated a floor and moving the cursor with the arrow keys switched between floors. These shortcuts are now ignored while the seed field or a button has the focus. Pressing enter generates a floor and leaves the field, escape leaves it without generating, and clicking the floor also removes the focus from the field, so the shortcuts work again right away.
