Currently the forensics-api-plugin provides the name and email of the author and the commit for a specific line as part of the blame. I would like to add the date of the commit here. This would help in determining not only who introduced a bug/issue, but also since when it is present.

In my eyes, this would include changes in the three plugins:

• forensics-api-plugin: Change FileBlame.java to include the date
• git-forensics-plugin: Implement the changed API to compute the date
• warnings-ng-plugin: Show the date in the blames table view

I would be willing to work on this and open pull requests, if this addition is okay with you?
