Moved the abstract SimConfig class to the framework as well as HeightmapGenHills.cs.
Added IUserServer.cs for the interface through which the sim will contact the user server for things like inventory details.
Users can now have a inventory and in sandbox mode each user is given a couple of test textures (note: should change the actual textures to better ones soon)
Can now change the texture on the prims.
Added a Local Asset server (a DB4o database) (although currently new created assets aren't backed up into it)
