Small changes

Changed code formating to my liking. Tried to add number index to menu.
Needs testing.
Updated the readme

I updated the readme and restructered it.
Added GPLv3 license and disclaimer
Merge branch 'master' into development
Added Adafruit Libraries, since global python packages are not working at the moment.

Inserted try:, except: and finally: statements for the menu code to handle LCD shutoff.

Tried to get lenth of dict and add it to a copy of itself, did not work. Lets try to get list length next.
