Removed backup_dir_mount_cmd option from Sysstem > server config. The option has been replaced by a script /usr/local/ispconfig/server/scripts/backup_dir_mount.sh. If this script exists, is exacutable and is owned by the root user, then it will be executed upfront of the backup jobs when the option "Backup directory is a mount?" is enabled in server config settings.

- Added missing option in centos dovecot.conf file

- Updated version number to 3.0.5.4rc1

- mail accounts not locked when client locked
- mail account sending and receiving lock separated
- fixed error in query
- fixed wording to match separeted locks

Fixed a bug in Opensuse installer (permissions of squirrelmail files)
Fixed a issue in smtp-authentication on courier-imap systems when custom usernames are used.

Updated apache_ispconfig.conf.master to allow access to phpmyadmin and squirrelmail on opensuse 13.1.

 - Reason:
   AddHandler fcgid-script .php
   does not only parse .php files, but all .php.* (e. g. .php.txt, .php.test etc.)

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

Moved check_recipient_access to the front. Blacklist for recipients is ignored on outgoing mails via smtp auth otherwise.

- Added function to detect the apache version to installer.
- Added support for apache 2.4 to vhots templates for ispconfig vhost and apps vhost in installer.

Fixed: FS#3350 - [Dovecot] Warning: mysql: Query failed, retrying: Unknown column 'filter' in 'where clause'

- Add config to clear php handler in apps vhost.

- 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.
