/* Make this gob "act" for one game iteration. "Acting" typically includes
one or more of the following:
o morphing the gob (changing its shape or class)
o setting the gob's velocity
o moving the gob
o interacting with other gobs
Act() returns:
o NULL, if the gob is destroyed,
o a ptr to a new gob, if the gob becomes a different object (as in the
tank to helicopter transformation), or
o the "this" ptr, otherwise
