[WIP] Nginx

[acburdine]

TODOS:

• test this on a live server with a url

The initial version of the Nginx service will not support:

• subdirectories
• existing config files

While the library I'm going to use nginx-conf should make integrating the above much easier, there are some edge cases that we may want to test for, which we can wait to do until after 1.0 ships.
