Scripts to publish jgit artifacts on Maven central

- you need an account on oss.sonatype.org and permissions for group id
  org.eclipse.jgit, see [1]
- install ruby [2] if necessary
- run download.rb to download the Maven artifacts from repo.eclipse.org
- then run deploy.rb to stage the artifacts on oss.sonatype.org
- follow [3] to close the staging repository which triggers some sanity
checks on Nexus
- ask community to test artifacts from staging repository
- if tests are ok release the staging repository as described in [4]
