Merge branch 'master' into 'master'

Master

Added metadata/org.billthefarmer.siggen.txt. I have not been able to do a 'git pull upstream master' to update my repo, as used to work on gitorious, so this repo, apart from my changes, is about a month old. I don't know enough about git to know if that will screw things up.
