switch the code to skelcd-control-openSUSE package

the package will be maintained in this Git repository,
(instead of OBS), all changes should happen here and the usual
Yast tooling should be used (Jenkins CI, rake tasks...)
changed versioning to a fixed number

removed get_version_number.sh magic script and related Rakefile hacks/workarounds
Merge pull request #5 from yast/change_to_skelcd
