lawnjelly d012a26e6a Portals - Fix default portal margin loading
The default portal margin is stored in the RoomManager. Previously this was propagated to Portals when the value was changed, and Portals each stored this default value.

This caused a bug during loading, if the RoomManager was loaded before Portals, the value was never propagated.

This PR makes the default margin a static value stored in the RoomManager, and the Portals now read directly from the static value when required, and do not store locally. This gets around the problem.
