Add contrib dir and bump.sh script
Add a contrib/
directory into the root of the project and a bump.sh script which bumps the version number in profiledef.sh (possibly works with -alpha or -beta releases as well) and commits the version bump.
Todo:
- handle semver (allow bumping major/minor/patch versions)
- maybe display the current version number and allow the user to just input the prefered version - easiest way
- commit the version bump and push it
- check for any existing changes and warn user (git should do that by itself?)
