Darcs (http://darcs.net) is an open-source distributed version control system. This patch adds support for local and remote Darcs repositories and the Darcs diff format.
I have tested the following on Linux:
* Adding Darcs repositories to Review Board
* Uploading and viewing diffs generated with 'darcs diff -u'
