Lighttpd reverse proxy fix

This changes cherrypy to use a mount location other than /, and then removes some code that adds a base url on your own. I don't know if this breaks anything, but I did snatch a movie. Mostly I'm worried about apache reverse proxying.

It still has an error if you go to
http://server/base

http://server/base/ works, and so does http://server/base/movie/
