Extended sub-uri support.

Adds new routing in routes.rb based on pod_uri. Assets are handled by a symlink
in public when using sub-uri. Various clean-up, removing thin and socket port
settings from server.sh (these are now taken from pod_uri and socket_port).

Basic functionality when setting a sub_uri like http://example.org/diaspora
now seems OK. Closes .http://joindiaspora.com/issues/737, and partially
http://joindiaspora.com/issues/391. Ports are yet to be defined and handled
in this context.
