implemented the patch supplied by Jan Vansteenkiste with the latest commit

I've changed the id HTML attributes of the check boxes. You can still group post requests on name attributes while using the id to keep the items unique in the DOM tree. i saw some commented code already being there but wasn't functioning, so i rewrote the original lines.
This only goes for type: CHECKBOXARRAY and RADIO

All parts are disabled at the moment. Please help update

Updated czech languages files

Added missing strings in some templates to english transalations

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!

- Fixed a login issue with safari.

The user can now "jump" to the webmailer and to phpmyadmin direct from within the corresponding list.
