Morse-code based RPN calculator (#164)
* Added Morse code based RPN calculator
* added manual and memory register
* fixed morsecalc negative indicator, edited header comment
* adjusted stack display controls
* Fixed warnings. Added calculator token aliasing ability. Added binary shorthand for numeral entry. Extended morse code binary tree.
* ui tweaks
* Update movement_config.h
* silence warning
