Cleaned and shortened to be more manageable.  There is no reason to keep all that luggage. Also use multi line sql so a human can read it.

- Changed FastCGI buffers for ISPConfig nginx vhost because otherwise you get "upstream sent too big header while reading response header from upstream" on OpenSUSE.
- Added 502 error page ("Bad Gateway").
- Added "fastcgi_intercept_errors on;" to nginx vhost template so that ISPConfig's error pages are displayed instead of the default nginx ones.

- Removed ufw configuration from installer to avoid "PHP Notice:  Undefined index: ufw in /tmp/trunk/install/install.php on line 251".
- Changed phpMyAdmin location in ISPConfig nginx vhost to allow phpmyadmin and phpmyadmin/ (with and without trailing slash).

- Installer adds ispconfig user to Apache group on Fedora/CentOS so that nginx/PHP-FPM can access /etc/squirrelmail and serve SquirrelMail for the ISPConfig vhost.
- Added session.save_path and upload_tmp_dir settings to the PHP-FPM pool definitions.

Changed PHP-FPM socket directory from /var/run/php5-fpm to /var/lib/php5-fpm because /var/run is cleand up on reboot.

- Added SNI config field in sysetm > server config > web.

1) Added DEVSYSTEM define in config.inc.php.master  defaults to 0
  If set to 1 classes can load as symbolc links, server.php now

2) server.php now resolves its require()ed files with an absolute
   path instead of relative.
