Review Board 2.0 supports associating commit IDs with review requests,

but it must be provided by the client.
RBTools now provides these commit IDs, when returned by the diff call.

These are only provided by Git and Mercurial right now, where they're

more useful and in higher demand.
The commit ID won't be posted if running on older versions of

Review Board.

Posted using the following scenarios using Git and Mercurial:

rbt post
rbt post HEAD
rbt post sha1
rbt post sha1 sha2

In the first three, the proper commit ID was attached to the review request.
In the fourth with the revision range, the commit ID was unset on the review request.
