Adds new analog pin literal block with options A0-A5. More pins are available on other boards, but this project targets Uno and Nano so we will stay within the range for those boards.
Adds new analog read block, returning the unaltered 10 bits from hardware. This is mutually exclusive with using a pin as a button input or any kind of output.
Unrelated change: adds a tooltip for the XOR/NOR block depending on which of these two options is selected.
AnalogPin.
