Appearance/discussion of Inferno units.

I tested it in the editor. I divided the demons into stacks of 100, 50, 30, and 10 and placed Archangels next to them (perhaps other units would yield different results, but I doubt it). The results were as follows: 100 demons – damage from the explosion is 162, 50 demons – 117, 30 demons – 90, 10 demons – 36. That’s what I got.
