Adding Generator For Single Prefab Structures

You can export the pieces yourself, but for a permanent solution we need to actually mark the areas as approved and edit the metadata on the primary Gallery server. So once you decide what areas to use, let me know so that we can change that on the Gallery server.
I believe you won't need webadmin access to the Gallery server for approving areas, and the metadata can be somewhat edited in-game, too, so you can do those changes once I raise your rank on the Gallery server.
