0.2

New year and 200+ stars, time to make a new release! What's new?

• new buffer which provides interactive tree view of all your images (equivalent of docker images --tree)
  • you can open it with f5
• new buffer which provides detailed information about an image:
  • layers, labels, tags and more...
  • there are multiple ways to access it -- you can hit enter on an image in main listing
• slimmer docker hub image (thanks to @andyshinn)

And some bugfixes:

• don't traceback when connection to docker engine cannot be established
• exit gracefully with a proper error message when running on python 2
