suggestion: relax "sword" tool type requirement

[phantamanta44]

sometimes, I would like to hit mobs with items that don't extend ItemSword. to this end, I would suggest relaxing the requirement for dark rooms, mob spawners, etc. to the item having an attack damage attribute. this allows you to:

• use fancy non-ItemSword sword -- e.g. tinkers' swords, ic2 nanoblade
• use other tool types as weapons -- e.g. maybe you prefer using axes

I just now noticed that the mob farm only executes enstabulation recipes rather than actually simulating a mob kill. that probably makes this suggestion a little pointless...
