BackupSuite_17.3

Changed in version 17.3
- changed the skin so it is more like the skin PLi-HD-FullNight (but not exactly, left some more room at the bottom of the skin)
- some small changes in the code, cleaned it up
- removed the ofgwrite binary from the plugin folder, it is now supplied as a package (on Openpli and all Open Alliance images) and is automatic installed when installing the BackupSuite
- gave the dog a bone and sent the dog to his pillow, in other words I removed the avatar
