Commands are interpreted when modals are active

[melville]

If you start VaultEd and enter a filename like 'test2' the 2 will toggle revealing the terrain. Similarly a '1' will turn lights on/off. Keypresses should only be interpreted by the active modal when one is active.

fixed by making these Function keys -- only keys that can't ever be used by other things should get intercepted for special processing in this way
