Update all references to Review Board 2.1 to say 2.5 instead.
Review Request #7074 — Created March 17, 2015 and submitted — Latest diff uploaded
We decided a while back that the next major release of Review Board would be 2.5, but we still had many bits of documentation stating 2.1 instead. This updates all those for the proper version.
Grepped through the codebase. Didn't see any more references.
