- Directive snippets can now be made available to clients; clients can select an available directive snippet for a website - the appropriate snippet will then be written to the vhost configuration file. This is useful for example on nginx where clients have no access to the Options tab of a website.

-Added a new option "Network Filesystem" under System > Server config > Web to toggle on / off the _netdev option for the bind mounts in /etc/fstab

Revert "Fixed: FS#3581 - Website unaccessible under some circumstances when using seo redirection *.domain to www.domain"

This reverts commit 5742e4c9.

Fixed: FS#3581 - Website unaccessible under some circumstances when using seo redirection *.domain to www.domain
(only for apache2, nginx still to do)

Changed web folder permissions in nginx setups from 711 to 751 to avoid (false) permissions warnings in log files.

- Fixed FS#3366 - Certain Custom php.ini settings seem to be stripped before being saved to .conf file.

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

Completly same functionality as VHost-Subdomain, not to disable if already existing vhostalias-somains in system.
