Implemented: FS#1252 - Add permission system based on user / password to app installer 

- I had to reorder the variables in language_list.htm for the link URL's
- Moved the lang_file var to the beginning of the URL to make it work.
- For some strange reason if you have &lang_file in the url it changes it to <_file.

- Fixed a formatting problem with suphp.conf and newer suphp versions.

Added a new module called "domain". With this module you can manage all domains (web + mail). Per default this module is not active. To activate it, you have to change the System Interface Config -> domains -> use the domain module. You also have to activate the domain-module for the admin (and for every client if you want). Important: you can not use this module if you have reseller!

Added a global default for the .htaccess allow_override setting.

Added Support for Sieve mail filtering language on dovecot servers.

Added a Checkbox to the language import form to ignore the version of the language file.

Added SOAP support for mail module. Many thanks to Arkadiusz Roch & Artur Edelman from Tri-Plex technology

Fixed FS#775 - Client can choose the servers for it's client 

Fixed: Missing server.ini config entries for vlogger and jailkit
Added: Admin interface server_config for vlogger and cron
