version dump to 0.2 - a couple of improvements:

- **feature**: output is now colored

- **feature**: a summary of matched hosts is printed before
  cmd execution

- **feature**: a summary of (un)successful cmd invokations
  is printed after cmd execution

- **bugfix**: improved error handling in case of wrong regex or ssh connection
  errors.

- **bugfix**: fixed erroneous import in setup.py that caused it to require all
  dependencies to be already installed.
