Improve Leonardo support.

Shift port by 1 bit on the Leonardo since PB0 is the RXLED and not
available for use via a pin.
Use a more generic method of shifting the bits since the Leonardo needs
1 bit shift and the Mega needs 2.

-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.
