Change the ballistomycete activation mechanic

Give ballistomycetes a counter, when it's at zero they have the slow
spawn rate (are considered inactive), when it's greater than zero they
have the fast spawn rate. Killing a ballisto gives +1 to any others on
the level, a ballisto spawning a spore subtracts 1 from its own counter
