- Updated Linux Distribution detection to recognize all wheezy sub versions correctly.

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.

Outdated warning for clamav is only shown with warning level in monitor when the daily.cfd update failed as well.

Fixed output of action name in debug mode (registerAction)

Revision 4063 changed the command of apt-get dist-upgrade, so it is no longer neccessary to call as it is the same one that is already executed before and we can reuse the output.

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
