This makes the user code easier to read:
brick.buttons()
brick.buttons.pressed()
It also opens up possibility to add features in the future such as:
brick.buttons.released() # return which buttons are not pressed
brick.buttons.clicked() # return which buttons were clicked since we last checked
This follows the same style as the new light API: some devices have specific instances of a KeyPad class.
A good example that nicely demonstrates the concept is the LPF2 RemoteControl, which has instances of a ColorLight and a KeyPad. It's added in this commit.
This is an experimental method for adding lights to some sensors.
And add workaround to make it show up correctly in the docs.
Also some doc8 formatting
