Wrong table used to remove deleted backup record for website. File gets removed but not database record.

Fix for mailrestore, to avoid confusion about web- and mail-backups with same ids

- Made sure SQL backups from servers that differ from the server where the website is on can be restored. A download of the backup is not possible in such a case, therefore I hide the "Download" button.

- backups: plugin checks mount point of wrong backup directory (e.g. /var/backup/web10 instead of /var/backup).

fixed zip-backup and restore, fixed log-output for restore mail-backups, mount backup-dir and try to create the maildir

- 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.

- Added "actions" framework in server to replace the functions provided by the core modules
- Moved system update function from remoteactins core module to software update plugin.
