Some first entries into the release notes list for the next release (WIP)
Modified versioneer to allow specification of manual versions based on branches

You can now define a lookup file explicitely mapping virtual version tags to branches via regular expressions and a reference commit from which the commit distance will be calculated.

Format of the file is

  <branch-regex> <tag> <reference commit>

The file is processed from top to bottom, the first matching line wins. If <tag> or <reference commit> are left out, the lookup table does not apply to the matched branches and the regular versioneer resolution (via git describe) takes place.

Current configuration makes "master", "staging" and any branch starting with "fix/" make use the default behaviour, all other branches (so basically all development branches) are defined as "1.2.0-dev"
