(nginx still missing)

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

- 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.

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

Catch situation where no basic awstats configuration can be found
and create a warning message.

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
