[company_name :: ] contact_name (username[, customer_no])

- Added [SERVERNAME] placeholder to webmail URL.

- Added "Rewrite Rules" field to the "Redirect" tab so that customers can set rewrite rules themselves on nginx.

  Along with this fixed some display problems with the combo boxes introduced in 3.0.5.
  Some fields were not correctly displayed with the predefined values if value and text of the underlying option element differ.

- Admins can now choose to be notified by email about debug, warning or error messages in the server process.

- Improved recognition of when a service (Apache, nginx, etc.) was really restarted/reloaded successfully. Checking port 80 is not enough because nginx reloads silently, ignoring faulty configuration files, but returns a value > 0. If we don't check the return value, nginx will refuse to start when someone issues a restart the next time.

 - added lost password button to login form
 - added back button to lost password form

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

  - send quota notifications each X days instead of each day
  - send notification when quota is ok again
  - cleaned up mail sending code

- Made remote IPs field for databases longer.

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

         client additional_template column might contain something like 15/20/211 instead of /15/20/211/

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