Fixed/Implemented: replaced intval() by $app->functions->intval() in all interface functions due to big number problem in intval()

If you change an auto subdomain of an alias/web-domain there has to be checked if a subdomain with www. or *. has been created already.

Implemented: FS#2427 - Allow wildcard subdomain creation on limit_wildcard = y 

Implemented:  FS#2422 - Use domain module when creating subdomains 
Bugfix: datalog was used in the wrong way on editing aliasdomains
Bugfix: missing datalog update for parent domain on editing subdomains

Added a workaround for a bug in courier maildirmake: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=501557

- 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.

avoid 400 bad request error if ssl is enabled and interface is accessed with http instead of https. Instead redirect to the requested page with https at the beginning of the URL.

According to FS#1982

- New feature: you can now add directive snippets for Apache, nginx, and PHP under System > Directive Snippets. These snippets are then available on the Options tab of a web site where they can be easily added to the respective textarea by simply clicking the name of the directive snippet.

- Implemented immediate change of theme on selection
- Fixed error message on incompatible theme
