Brain blob making blobs work together.

Pondering boss monsters, and thought of one of my favorite game bosses ever, phalanx from Demon's souls.  For those who haven't played, it's a large, tough pile of goo (sound familliar?) that has little to no combat ability itself, what it does do is control a swarm of regular monsters, each of which is a smaller blob with a shield and a spear.  Individually they aren't that tough, but in a large group they can be quite tricky to deal with since they all stay close together.
Anyway, it's not an exact copy, but I tried to reproduce that feeling of the enemies working in concert, and I think it was moderately successful.
Since I astyled monattack.cpp, you'll need to look at de182dd for the functional changes, if that's too much of a problem I can pull out the astyle commit and PR that after this one.
