[Bugfix] Pods not being displaced by escape shuttle

[Grayshift]

Hello! Time to ruin fun. Replace shuttle_controller.dm:120-135 with the following code to boot pods to the east rather than south. Also consider upping the damage ex_act does to pods in vehicle.dm - a severity 1 explosion only does 65 pod damage, enough that an escape pod can survive it. Also: shuffling things to the east on Destiny ought to be fine, too.

Edit: Found a couple issues, and now respects map and will punt items in the correct direction. New code:
