Replacing Equals() with StartsWith() in AutoClosingDoorsManager.doorToBeExcludedFromAutoclosing() so that users may exclude groups of doors by name

Changing the DoorEventWatcher to make use of the DoorStatus enum, which I didn't know about

Adding the auto-sealing feature for airlocks

Updating the createAirlock method of the AirlockManager to allow using the same door in two airlocks, so that multiple airlocks can be chained to create an airlock with 3, 4, 5, ... multiple doors operating in sequence.

Adding new override for the createAirlock method to allow easy creation of a 3 doors airlock.

Added option to exclude doors with certain names from the automatic closing doors list
