- Implemented FS#3308 - PATH placeholder in directive snippets (placeholder is named {DOCROOT}, like for nginx).

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

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.

Reverted SVN trunk back to revision 3938 to remove changes in default theme an a replacement of the ispconfig logo.

- Added backup size to web backups

Ensure that folder protection is deactivated for the path of the base website when deleting a vhostsubdomain.

Bugfix: $app->system->unlink function had wrong parameter name, no files were deleted ever

- Fixed missing templates and language entries
- Previous subdomain mode can be used concurrently
- Changed log path to a more convenient location
