Explicit room-creation using protocol's own "room" template is now
supported.
Two new protocol API messages were added― IM_CREATE_ROOM and
IM_ROOM_CREATED, which are parallels to IM_CREATE_CHAT and
IM_CHAT_CREATED. Rather than the latter two, though, these are wholy
based on the "room" template― their slots are completely determined by
the protocol.
A generic "TemplateWindow" was created, which allows catch-all creation
of windows that leverage protocols' templates. It's used for the
room-creation window (Chat->New Room / Alt+N), for example.
At some point, it ideally should replace even the JoinRoom window, and
maybe others.
