Added carriage return and newline to the beginning of several CLI command responses
Add command mode command M - set command mode WPM (command mode now has a speed setting independent of regular keyer speed)
Added OPTION_SIDETONE_DIGITAL_OUTPUT_NO_SQUARE_WAVE which changes the sidetone line to go high/low rather than output square wave, for driving an external audio amplifier
Lots of new functionality in FEATURE_TRAINING_COMMAND_LINE_INTERFACE

Norwegian language support for Wordsworth training: OPTION_WORDSWORTH_NORSK
Enabling this feature and an external toggle switch adds switch control
for playing cw sidetone. The feature will override software control of
sidetone (\o). Switch status is displayed in the status command.
Eliminated FEATURE_DIT_DAH_BUFFER_CONTROL code; it's compiled in with core code now. Also depricated OPTION_DIT_DAH_BUFFERS_OFF_BY_DEFAULT_FOR_FEATURE_DIT_DAH_BUFFER_CONTROL
