Set variables before the 'stop editing' section

Some random notes:
X-Real-IP, X-Client-IP : client (browser) IP in non-proxy case
X-Forwarded-For : client IP in proxy case
X-Forwarded-Host : Server name in proxy case
X-Forwarded-Proto : https/http in proxy case

PHP:
SERVER_PORT - apache sets this of the port it got the request on
HTTP_HOST - apache sets this to srver name. in cloudron, we actually set this in nginx
    when doing proxy pass. One can also use the X-Forwarded-Host above.

Wordpress:
HTTPS - set this to generate https urls. Otherwise, it is based on SERVER_PORT
HOME_URL, SITE_URL - variables used to configure wordpress location. when unspecified,
    this is computed from HTTPS variable and HTTP_HOST

Wordpress saves lots of options above in DB (!) including HOME_URL and SITE_URL. These
are saved at installation time and can be updated from admin pages.
