post-review modification to recognise moved/renamed files in Perforce repository and treat them similarly to deleted files

Review Request #1654 — Created June 10, 2010 and submitted — Latest diff uploaded




Files that have been renamed or moved in a Perforce depot appear with the 'move/delete' action, and not just 'delete'.  This modification ensures that post-review recognises these correctly and removes them from the diff listings.
Tested with latest Reviewboard install, against a production perforce server.  The script now correctly does not show renamed/ moved files in the diff lists, where they were appearing before.
