Selective firing for blasters and mortars

[Karsten75]

I'd like an option (map-wide or per tower) to tell a blaster to not fire at multi-layer creeper and to tell a mortar to not fire at single-layer creeper. I find it annoying if I have to move a mortar to a different point jus tto get it to stop firing at a single layer of creeper that it somehow just can't wipe out when I know that a blaster can do it no sweat. And also, no point if I want a blaster to keep a ledge clean for it to fire into a deep pool of creeper next to the ledge.
