changed 16-bit level micro chunk value type from unsigned to signed

This change allows for saving and loading negative 16-bit values in
level files (like negatiove values for "gems needed", for example).

As a result, 16-bit and 32-bit micro chunk values are always signed
now, while 8-bit micro chunk values are still always unsigned bytes.
