Added new theme. You now can change between 64px size icons, 32px size icons (the default-value) and no icons

Added a new theme called no_navimg. This template removes the icons from the top-Navigation if you don't like them

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!

- Set a fixed column width for the buttons in the client and reseller list.

Fixed: FS#1118 - [client_id] is not resolved in .php-fcgi-starter

Added European Portuguese translation. Many thanks to Miguel Almeida to provide this language file set.

- Added a missing language string for the website form.

- Added a robots.txt file in the root directory of the ispconfig interface to prevent it from being spidered by search engine robots that follow the robots excusion standard.
- Fixed a error message in the installer.
