- Added: remoting will return the template_additional param for clients in the new style - compatible with old style

- Implemented:  FS#1312 - disabling a whole client
    -> see bugtracker comments for more details
- Fixed:  FS#3060 - Subdomain vhost ip update on web domain update
- Implemented:  FS#3078 - Change client template system: delete specific template from limits 
    -> including link in billing module to link specific assigned templates
- Fixed:  FS#3058 - Error in mail quota calculation when changing tab in mailboxe configuration
    -> quota limit no longer checked if it was not changed
- Fixed: Deleting a client's template could mess up his assigned templates
- Added: remoting functions to change client templates the new way

- Implemented: Virtual columns (columns that are not in the db but shown in the list) can now be sorted if defined correctly

- fixed permission of vars starting with _

  ->setLoop('abc', $content);
  will automatically add a
  ->setVar('_abc', count($content))
  IMPORTANT: template variables and loop names starting with _ are not allowed anymore, those are reserved for the counters!

- Lists can now be created from more than one database table (including sorting and searching) // needs more testing!

Reworked database user management to fix FS#2918 - multiserver - remote access db passwd not changed , when changed access from IP to % and vice versa
