Merge User-Interface and Interface pages
What's currently in Interfaces should probably be moved to either Interfaces Wishlist or what's currently in User-Interfaces.
Then we sould make Interfaces or User-Interfaces a redirection to the other one.
Edit: I just noticed there's #23 (closed). I'm still not sure what would be the proper way to handle that. The discussion probably should be on the other issue anyway. Closing.
