Suggestion: Additional Room Tags

[Pinstar]

In the directory, rooms are given some obvious tags "Green Room" "Dead End" etc, which indicate which ones might interact with other mechanics. However, these tags don't cover everything. Which rooms spread steam? (For Boiler Room) Which rooms contain a fireplace? (For Vera). Having these tags added would be useful so it is crystal clear which rooms trigger which effects.

Like...does the furnace count as having a "Fireplace"?
