explosive/mine damage for shove fall. AI still seems to refuse to bat dud mines :(

Also have AI consider mines that will almost certainly be duds by the time he gets to them. I'm mostly using it to test AI behaviour w/ firepunch/whip/bat on a mine-heavy map.

oops

try to guess at barrel state. prob should flag it..

ignore non-hedgies here. could be useful, but Hammer needs to be taught to consider it. (hammer + explosives on a bridge could be neat)

trying to make AI aware of mine/explosive break point. also remove redundant test.

only rate subs if significant. still very much need correct fall+damage esp given different knocks.

Make hogs aware of dud mines and explosives. Still a bit more needed.

merge :P

Apparently resetPosition is not needed at all (/pause doesn't call it and works the same)

CheckGearDrowning could delete hedgehogs gear! (CheckGearDrowning -> ResurrectHedgehog -> FindPlace). Fixes bug #620.

Make AI more active in multiattack game mode

this should improve consistency of mortar cluster spread and snowball knocks

fix bug that locked unlocked campaign missions, see issue #452

fix nil comparison error, see issues 470 and 601

this is fairer
