first draft of a release script

Hey,
This is a first draft.
Some notes:
* version names must be using major.minor.patch, e.g. 0.97.0 (this can be easily changed)
* I commented out push commands, so it doesn't do any bad things before you are certain it works for you
* with the current state of the repository (master branch pointing to v096) this script will fail with merge conflicts, so I suggest forcing master into common root with develop just before doing first release with these commands:
  * `git checkout master`
  * `git reset --hard 7c10c8ac26`
  * `git push --force origin master`
