Updated apache_ispconfig.conf.master to allow access to phpmyadmin and squirrelmail on opensuse 13.1.

 - Reason:
   AddHandler fcgid-script .php
   does not only parse .php files, but all .php.* (e. g. .php.txt, .php.test etc.)

Changed: apps vhost is now a template (for apache version)
Changed: template if tags can now be of format 'version' to make version comparisons (e.g. 2.12 > 2.2 !)
Changed: New apache 2.4 syntax for deny from all (-> Require all denied) etc.

- Fixed FS#2441 - FastCgiExternalServer: redefinition of previously defined class "/usr/lib/cgi-bin/php5-fcgi".

- Added check for the apps vhost to find out if the default PHP-FPM pool uses port 9000 or the socket /var/run/php5-fpm.sock.

- Added overtraffic notifications to traffic quota system (part of FS#2059 - Extend Traffic quota system)

Fixed (partly) FS#2310 - Template switch not working in mailuser module, for dashlets and the login page
