Added awesome stuff!

As discussed, I added blinkstick command line tool to control pretty much every aspect of the device. Didn't change anything in the API, but removed all examples and moved them over to the wiki as the command line tool now takes care of everything. Now it's super easy to control blinksticks! 

I even added the command to create udev rule. Ideally it could be run during the installation, but may be too much invasive into the system so I would rather leave this for the user to decide if they want to add the rule or not.

I'd appreciate if you could have a quick look at what I wrote there just to make sure it makes sense, bump up the version number of the pip package and deploy. I think I should learn to do this myself too. A task for Monday maybe? :)
