Only force G and M codes toUpper
Summary:
Users need to enter some case sensitive info such as wifi passwords Spec (https://reprap.org/wiki/G-code#Case_sensitivity) Internally AtCore does not force case since our GCode object sends them back correctly. Allow users to input case sensitive text into command widget but force G and M codes toUpper.
