repr classes as <class 'module.Class'> like Python

- We were using "<type ...>" like Python2 does for built-ins?
  But even Python 2 called user classes "<class ...>" - Python 3
  calls both built-ins and user classes "class".
- Check if there's a __module__ name and use that as well, now
  we look even more like Python!
