Billinger country trade v1.0

Since I was looking for another country trade for my Landwehrkanalmap me the old Billinger of KA88 is eye-pleasing.

Several people have Billinger on the already tried, unfortunately always with the known texture errors. I have taken the model in Maya completely apart and put the new textures.

Also there are some very small changes to the original:
- Under roof was covered with a wooden texture
- Some components that have not appeared to me to scale reduced etc.
- Floor and the decorative material are now separately so everyone can use what he wants

Thanks again to KA88 for release.
Have fun with the building
