Nginx support

[levifig]

I'd gladly contribute the nginx config templates. The passenger gem installs nginx under /opt/nginx (default) so we could go with that and allow path change only if requested.

From there, I think a fork of the gem for production servers would be awesome. It would allow one to manage new hosts and files instantly from the command-line. I had a similar gem sketched out but if we could work together, things would work a lot better! ;)

We released a gem about a month ago. Please check out the experimental branch for the code.

Keeping the internal and external version of the ppane gem in sync might be a bit of a pain because of special needs for the version bundled with the prefpane. For example: the gem currently has to untaint strings because ppane runs in a special setuid mode when called from the prefpane.
