[Bug] Quorum doesn't build new structures at RCL8

[duckymirror]

With the factories update the CONTROLLER_STRUCTURES has been modified. The result is that Quorum expects a factory at PRL7. Because they aren't included in the layout yet it can never reach PRL7 and doesn't build structures after that.

Fix

Modify the room layout to include a factory

Workaround

Add STRUCTURE_FACTORY to the skipStructures array in extends/room/construction.js

[tedivm]

Another option would be to whitelist the structures looked at for determining room level, which would make the code future proof should other structures get added.
