main feature to single vob

Please see the attachment for a patch that adds an option to write the main feature to a single VOB. My personal use-case for dvdbackup is most often as follows:

1) dvdbackup -F to several vobs
2) cat *[1-X].VOB > single.vob (skipping *0.VOB, the menu)
3) transcode to modern format with a tool like handbrake

With this patch one can do this for example:

dvdbackup -i /dev/sr0 -Fg

and get a single 'Title.VOB' without menus and ready to feed into the transcoder.

Thanks very much -
