Dev/jpsnyder/demo/instructions (part 2)

- Fixed up hardware hacker demos to only use a single cell, (either 1 LED matrix, 1 accelerometer, or 2 buttons)
    - Created special test programs that show the accelorometer and buttons working in a pop up terminal window on screen

- Created a reset.sh script that resets the demo python programs for the IDE
- Added a temporary fix to detect if CREATOR or GAMER lid is being used (ground pin 14 on the CREATOR lid)
    - now the games can call led_matrix.init_grid(2,2) and the API will handle the correct thing for either lid  (THIS NEEDS TO BE TESTED!)
- Added proper instructions to instruct users to run correct programs and run select correct lids.
- TODO:
   - instructions need to be proofread
   - wiring diagrams need to be added
   - demos need to be thoroughly tested (need to walk through all the demos)
