Moving Phabricator from /var/www to /opt/phabricator

Looking at other Images like Drupal & WordPress it seems that using (or abusing) /var/www which is specific to Apache, is no longer an acceptable pattern.

This makes to me, so I've moved Phabricator from /var/www/phabricator to /opt/phabricator. This makes the Phabricator more consistent with other images that people are used to. I realize this might break volume mounts if you are using them.

Make sure you update your volume mounts when you upgrade!
