Gar mesons and satchel revert

Reverted the name of the satchel to 'industrial' satchel. it was engineering before because i was going to add a mining/atmos satchel, but i dropped that and so I'll keep them back to as they were before.

Added GAR MESONS! which will be available in the equipment locker once this PR is merged:
