City Backgrounds added

Thanks to information I've received today I've now been able to add the four City backgrounds into the project. There are different mountain range backgrounds within the City depending on whether you're facing north, south, east or west.

I'm now having a go at adding the door signs for the various City establishments (E.g. guilds, shops etc). I thought I'd come up with a quick way of dealing with this but I've still got some work to do as the signs are not appearing from the outside of the shop only the inside! I'd forgotten how the City map structure works. My map structure can easily accomodate additional textures to deal with different wall types but would require me to edit lots of doors manually which I don't want to do if I can avoid it.
