Wuzzy's changes to climbhome w/ some tweaks by me

Reset max team health after script may have screwed with it on start. Maybe a script max health reset function could be useful too. Set climbhome hogs to invulnerable while not their turn if needed to avoid accidental mine/dead hog damage. Tweak cake fire boom a bit.

Move cake FollowGear to Attack like most others, remove the gmAttack clearing which is also done in Attack.

duplicate the ammoshove block into the falling fire area - this will make falling flames take out hogs in saucers, on rope, etc. no more dodging your own napalm strike by taking to the skies...
