Two mutators:
-Quakes: random earthquakes (random intervals configurable via ini)
when they happen can shake around player, bots and decoration (including
much of the loot and some levers/buttons, too)
-Spiders: configurable (maximum) amount of spider hatching, destroyable eggs added
to the map in random places. Maximum number of spawned spiders configurable
as well. Spiders grow (or at least mature to the point at which they can lay new eggs
if max amount is currently not met.
