Airlock Canister Starting Pressure Doubled (#19967)

The airlock air canister subtype starting pressure doubled (now around
600), this will hopefully lessen occurrences where the canister has
insufficent air to operate (and thus be stuck closed).

This appears to happen for ships spawning docked, in the future it
should be looked into allowing an 'override' for docking to dock despite
air difference
