Merge branch 'feature/spaces-and-cleanup-0.3' into 0.3

* feature/spaces-and-cleanup-0.3:
  Minor modifications to get tests back to work. Two tests are failing in the latest git version, would have to dig into it
  Adjusted required versions of pre-requisites, now the majority of the tests work
  tabs to 4 spaces - this won't make integrating the patches easier, but it's probably a good idea to go a little more pep8 (and fix sins of my youth ;) )
