Stops the exponential hell of petsplosion happening more than once a round it turns out we didn't need 6000 mice

Reduces the lava event from "lets slay all idlers and stop all action for 2 minutes" to "lets greviously wound all idlers and stop all action for 30 seconds"

Makes summon magic/summon guns work fine without a mob attached, this prevents a runtime and some odd messages to the admins

Makes the inviciblity text jive better.
Fixes up some silly problems with cursed items:

Things won't be called cursed cursed cursed cursed cursed cursed cursed cursed cursed cursed cursed cursed foo's anymore

Cursed Katanas can't get stuck in any other slots now

Things that destroy your ability to go into space now won't spawn on you at all if you happen to be in space when the spawning occurers, but hey don't idle in space just to avoid a luchador mask, magicarp are still a thing.
