othermod gamepad v2.0

This is a complete rework of the driver. It is now written in c instead of python.

Added the MCP23017, so the driver now creates 16 buttons and up to 2 joysticks.

The setup is simpler and allows the driver to be loaded on bootup.

Initial Release from Jan 16, 2018

This release just archives the current state before I upload a new driver
