Port OBS related code to Github

[dagwieers]

We have to port the OBS (OpenSUSE Build System) related code to Github for releasing packages for various distributions.

For this we need to readdress the versioning of the project as Github is not based on a global revision like subversion. The proposal is to use an official version from the release and a daily timestamp. Another change will be the package name for (daily) snapshot releases to rear instead of rear-snapshot.

Both changes will make normal releases and snapshot releases interchangeable:

rear-1.13.0
rear-1.13.0-1.git20120528
rear-1.14
rear-1.14-1.git20120812

There is also no need for the third digit, so we might as well stop doing the third digit (until it is needed). This means that our next release will become 1.14 and if there is a need to patch 1.14 (because a major bug is backported to that release) we will release 1.14.1. This gives us the future flexibility to support older releases.

The first step, to have a Rear project on OBS is already performed by Schlomo. You can find our new project location at: Archive:Backup:Rear

The we must make sure that the snapshot and release packages go to
different repos on OBS. Otherwise people won't be able to install the
release. That was the original reasoning behind the rear-snapshot package.

Dag,
did you finish the git2obs.sh script? If it is not yet finished can you push it into git so we can have a look and try to finish it?

@gdha There is nothing in my scripts that even works, so there is nothing to share. It will probably confuse you even more :-( I did not have the time to look into it after LinuxTag 2012.

My focus is now on the Makefile, then OBS, then automated testing and potentially after that reorganizing the tree. We could do a release when the automated testing is useful. At some point I would also like to re-indent all files and make that Bash coding style document. But life's too short :-(

@jhoekx fixed it !
