As a user I should be able to add notes to GitHub, and the DVCS connector would make updates to the JIRA issue.

One common scenario is:

1. Make a commit in GitHub, and the developer forgets to enter the the JIRA issue in the comment.
2. DVCS scans the commits and doesn't add the commit to the JIRA issue because there was no issue entered in the GitHub comment.
3. The developer goes back to GitHub, and adds a comment/note with the JIRA issue.
4. DVCS should scan subsequent comment/notes and add a commit to the JIRA issue.
