Truncate the "Signed-off-by" part of commit messages throughout site.
Created by: drollins
All instances of commit.safe_message (including dashboard spec) replaced by mew method commit.safe_message_no_signoff; you may wish to simply incorporate the changes into safe_message itself... but that's up to you :)
