Changed mode of web folder from 0710 to 0711 to make it comaptibe with servers that use NFS for /var/www.

- database users
- email forwarders and aliases
- clients

- Add missing configuration inclusion (vhost files) to apache config

Changed: apps vhost is now a template (for apache version)
Changed: template if tags can now be of format 'version' to make version comparisons (e.g. 2.12 > 2.2 !)
Changed: New apache 2.4 syntax for deny from all (-> Require all denied) etc.

- Added email message templates.

- Fill IP select fields with IP from correct server even if the user's default web server is another server. Otherwise if the user opens the web form, the wildcard * is selected, and if he changes the tab, the wildcard is saved instead of the correct IP so that the website will no longer work.

Outdated warning for clamav is only shown with warning level in monitor when the daily.cfd update failed as well.

- nginx pm settings: values were limited to 3 figures (so max. value was 999), increased this to 6 figures.

- Added section toggle for client limits

- Resellers can use templates for their clients.
