URI that will be linked with every Commit added to a Rally Work Item's Changeset.
If you have a web-accessible repository browser and wish to deeply link into that system with commits linked in Rally Changesets, use the ${revision} variable to do so.
For example, if you want a commit with hash 12ab34cd56ef to be accessible at http://github.com/your-name/your-project/commits/12ab34cd56ef then you would set this property as: http://github.com/your-name/your-project/commits/${revision}
