Backup.sh : Add command line option to backup all data.

[OWarneke]

It should be possible to create backups without the interactive mode.
This way it is possible to more easyly creat regular backups.

e.g.:
Add command line options as follows:

"Backup.sh -S /media/rfs/internalsd/ -T /media/rfs/externalsd/ -C ConfigBackupPaths -M SettingsFile-D true -L true"
-C Config "SettingsFilePath"
-M Storage Mode: "Upperdir / PCWE / SettingsFile"
-D Store DeviceData "True/False"
-L Store LicenseFiles "True/False"
-S SourceLocation /media/rfs/internalsd/
-T TargetLocation /media/rfs/externalsd/
