Shared nginx configuration for multiple servers

[Michael Shadle]

include isn't supported inside of "if" either, I believe.

I wanted to do conditional includes before - but ran into a wall.
Someone I believe replied to me off list and said they were trying to
add support for that though.

(I think it might be how the configuration parser works. $hostname is
unknown when the server starts up, and it includes all the includes at
the time of start?) I don't know.
