This update primarily drops the legacy Plasma API in favour of using the new APA102 Python library to get right to the point.
Additionally support has been added to disable the LED and Button, which will avoid any GPIO set up for either of these devices if those pins are desired for other add-ons.
- Replace Plasma API with APA102 library
- Add support for setting LED global brightness
- Add support for disabling button and/or LED
- Move packages/requires to setup.config, minimum version now Python 2.7
