-Modified Ore generation, it should spawn ores in the mines now. Will be more numerous than normal but it's a guarantee they will spawn.
-Modified 'PrideRock.DMM' to not be a endless death-trap
-Modified 'methlab.dmm' to have stuff in the safe.
-Modified 'Oldhotel.dmm' added the correct oven
-changed name of abandonedhome.dmm to lonehome.dmm see if that fixes travis (or something)
Created a global list to track base turfs for explosions/shuttle moves.
