moves rewrite_rules to location_header

[paschdan]

in some vhosts i need to have rewrites inside fastcgi locations.

this PR adds rewrite rules to the fastcgi.erb file.

for the specs i had to use regex to get the tests going, i am not sure how to write the test in better format.

Awesome. I think this should be ok.

@3flex whaddya think?

I think it's a good addition, but it should go in templates/vhost/location_header.erb instead of just the FastCGI template so it can be used for all location types. Though now I look I see the same code in templates/vhost/locations/directory.erb and templates/vhost/locations/proxy.erb...

@paschdan would you be comfortable removing it from directory.erb and proxy.erb and moving it to location_header.erb? If not, then @jfryman I say merge as is and we can look at tidying that up later.

@3flex i could do that, yes

Sweet, the templates look good. One last thing - can you please move the test up to the section starting around line 35? That way it tests the header template, not just the fastcgi template output. Then squash commits to one if you could.

Thanks for the contribution!
