Note: The mod_proxy_fcgi that ships with CentOS and Ubuntu does not support sockets yet, so all php-fpm connections are done by IP.

- changed hhvm handling to match stable branch (FilesMatch in Directory sections) - added changes from stable accordingly

Revert "Fixed: FS#3581 - Website unaccessible under some circumstances when using seo redirection *.domain to www.domain"

This reverts commit 5742e4c9.

Fixed: FS#3581 - Website unaccessible under some circumstances when using seo redirection *.domain to www.domain
(only for apache2, nginx still to do)

- Changed vhost.conf.master as php-fpm was not working after commit "5a6670bd".

- fixed vhost template. website settings were overriding handlers of apache config files, e. g. roundcube

- removed [PT] flags as it is causing problems with some php applications due to information in SCRIPT_NAME and PHP_SELF

@see http://httpd.apache.org/docs/2.2/en/mod/mod_actions.html#action

(nginx still missing)

- Enable php-fpm socket mode as default.

This will enable all functions, previously disabled in php.ini, like exec which ispconfig needs to functions properly.

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.)
