Engine loader now calls a proc to init Atmos machinery after loading the
submap.
Use time helper library to hopefully bring the engine select timer in
line.
Engine spanwer now waits 30 seconds before spawning the engine.
Engine spawner no tells people when it's going to spawn an engine.
Engine spawner alerts the rest of the station to what engine was
selected.
Engine spawner no longer outright players or observers, it gibs them
instead.
Minor streamlining of some code bits.
Lays down the ground work for players being able to select the engine at
the start of the round.
Proof of Concept using a pickEngine() proc that can be called from the
mapping controller.
