Added dummy controller

Added a basic Dummy controller to allow for absolutely minimal testing of the JSON API and other parts of Lightbox that need a controller to work.
Fixed small bug with /info

This is related to issue #3. Fixed reporting to address the serial connection as opposed to the box itself when it reports serial device and baudrate.
Updated API utils to use ControllerInfo API

All assumptions with regards to the number of outputs are now based on actual reported information from the API. This means that the correct number of strips can be driven without having direct control over the controller hardware.
