changed translation of sites from "domains" to "Internet-Auftritt", because we also have a MODULE called "domains"

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.

Added new "DATE" datatype which uses the native mysql date format instead of tstamps in tform library. The old tstamp datatype as been renamed to "DATETSTAMP".

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

Fixes Encoding to UTF-8 and Add Some New Strings

Merged all language files.

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