hurnscald rehaul (server-side)

this branch enables new features in hurnscald

at the moment it enables this:
- new room in hurnscald in the store/shop/dyer building (previously inaccessible)
- Jack the lumber's house is now the GM lounge (only accessible if gmlevel > 1 || debug )
It would be redundant to have two debug npcs close to one another;
there is an xmasdebug in 017-9 and one on 020-1
