v0.14. Rearrange DEBUG functionality, disable by default.

Browse Source 
v0.14. Add ‘DEBUG_MENU’ which can be uncommented to enable the basic
debug menu with the ability to run a capture / dump the data etc.
DEBUG and DEBUG_MENU are commented out by default to save RAM.

Debugging
=========
You can uncomment the '#define DEBUG_MENU' line to add some diagnostic menu
options for capturing or dumping the capture buffer.
You can uncomment the '#define DEBUG' and '#define DEBUG_MENU' for a couple
extra menu options and logging of the received commands. The DEBUG option
is generally only useful for development, while the DEBUG_MENU option is
good for troubleshooting when the logic_analyzer sketch isn't working for you.
Both are disabled by default to conserve RAM for improved stability.
