Add support so that setnodeloc and floormaps can be used on the
new_nodes table. Thought it would be easy, but ended up doing more damage then I expected; oh well. New nodes show up in "gold" color (not listed in the legend). I added a link from the newnode_edit page. Rob will need to arrange for a location_info entry to be created when a new node is made live (but only if building/floor are not null).
