Fix changelog heading
Removed empty placeholder headings under the 0.3.1 section
Released v0.3.1
A couple small fixes to the release procedures made while making the v0.3.1 release.  First --distribute should not be used with virtualenv anymore, as distribute is deprecated. I also removed the mention of backport-* labels, the use of which seems to have been abandoned for now (it may come back in the future but for now it is not really used)
