Support external mounted partitions

[framps]

As of now only the boot and root partition are saved in normal mode. Partition oriented mode can be used to backup additional local partitions but they have to reside on the same device as the root partition.

It' quite common to have additional data on other external partitions (not on the root device) which also should be saved.

Right now tar and rsync uses option -X which causes them to stay on the same device. Either -X should be removed and all external mounted partitions excluded if they are not included in an option or the included partition will be saved in a following step.

Backup

1. An additional configuration option DEFAULT_MOUNTPATHS_TO_BACKUP and option -X allows to define a list of mountpoints of partitions to be included in the backup. The backup type selected for the OS is used also to save these partitions (tar or rsync). Backuptype dd doesn't support additional partitions.
   Example: DEFAULT_MOUNTPATHS_TO_BACKUP="/influxDB /mnt/videos /mnt/photos. Default is an empty number of mounts to backup.
2. The additional partition backups are stored in the backup in /raspiBackup/mounts/<mountpoint>
   Example: /raspiBackup/mounts/influxDB /raspiBackup/mounts/mnt/videos /raspiBackup/mounts/mnt/photos
3. Directory /raspiBackup is just used in the backup directory and will not pop up on the restored system
4. The partitions are saved in the sequence they are defined in the option
5. Only local mounted devices are supported. Network mounted partitions (nfs, samba, ...) are not supported.
6. This new feature is available only in the partition oriented mode.

Restore

1. The restore uses the same mountpoints as used in the backup and can be derived from the subdirectory name used in /raspiBackup/mounts/<mountpoint> in the backup. If there is no partition mounted on any mountpoint the restore fails. This is tested before the restore starts.
2. Configuration option DEFAULT_MOUNTPATHS_TO_RESTORE will allow to define which external partitions should be restored. Default is an empty number of mounts to restore. Corresponding pption is -X .

Installer

1. An new configuration menu option C10 Additional partitions will be added which allows to prime the new configuration option
2. A list of mounted partitions other than /boot and /root will be presented and can be selected in a selection list. This list includes mounted local partitions only.
3. Only local mounted partitions are allowed. Any network mounted partitions are ignored.

Just to double-check, this means that I would be able to include my external hard drive mounted to /media in the full backup, right? Because that would be amazing, it's the only thing I'm missing from raspiBackup
