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.

do not change parameter order in old functions

--------------------------------------------------------------
Feature can be activated over admin mailserver settings. when activated websites uid is used instead of standard vmail-uid. this only takes effect if web and mailserver are on the same server, otherwise it will be old behaviour. switching this setting when mailboxes exist doesn't matter. Mailboxfolder will be created with website uid for this. access of postfix and dovecot now works over mysql-table mail_user. virtual_uid_maps is changed from static to mysql-table. for dovecot<->postfix communication protocoll is changed vrom lda to lmtp. disablelmtp-column is added to mail_user-table. uid and gid can be overwritten by remoting.
ONE OPEN ISSUE: since remoting has completly changed and mail_user_add function is missing at the moment, this function now was inclulded again. it is important to add the both new lines to the future function and then remove this new one.

Outdated warning for clamav is only shown with warning level in monitor when the daily.cfd update failed as well.

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

- write sieve filter to sieve subdirectory into ispconfig.sieve
- link .sieve to sieve/ispconfig.sieve

 - refresh, retry, expire and minimum were missing in the SOA record which was/is OK
  because pdns has defaults for this, but this gives the user
  the full options which are configurable from the UI

+ drop/replaced pdns service reloads
 - the initscripts reload function was called which internally does 'pdns_control cycle',
  which is a quick service restart. This is no needed in pdns to
  load the new zone data. All updates are available without service reloads.
 - to be sure the zone data is really loaded 'pdns_control rediscover' is called
 - for pdns versions starting from 3 (DNSSEC) all zones must be rectified, implemented this using pdnssec.

+ send notify to slaves
 - implemented using pdns_control,
  this enables zone transfers to slaves (maybe this never worked before, because auf the service reloads)
  hint: use supermasters table on slave server for zone autodeployment, but you need an extra cleanup script
  for deleted zones for now

+ fetch Slave zone from master
 - call 'pdns_control retrieve <zone>' for new slave zones

+ added fix from FS#3121

+ code cleanup

add amavis-configfile-location for centos 6.4; add amavis-initscrip-name for centos 6.4; fixed missing private_key in mail/mail_domain_dkim_create.php

- Added options to use a mounted backup directory. This allows for remote backups, e.g. vis sshfs to a backup server. The backup script checks if the backup directory is mounted, and if not, tries to mount it.
