Add --branch option to post-review.

Review Request #586 — Created Oct. 10, 2008 and submitted


Review Board SVN (deprecated)


Added "-branch=BRANCH" command line option to post-review to allow the Branch field to be filled out from command line submission of a review.

Review board was refusing to import my difs. Thanks to Christian Hammond for the explanation.
/trunk/reviewboard was the location details I needed.
Tested against a local review board server to confirm the expected string value is added to the Branch field.
  1. Looks good. Committed as r1545.
