Set the Reposity links to actually install Phorge, Update Documentation links to the new Website.
Notes:
- Github Mirrors are not set up. Use one anyway? Or just use the Repos at we.phorge.it?
- Documentation Links still contain "phabricator". The Docs are changed, but the Diviner Books are not rebuilt. (Add a Cronjob or do it after every Commit?)
- mysql-server is not included anymore in Debian environments. Should mariadb-server be used?
- Should we print somewhere that Phorge is a Fork of Phabricator?
