TUNE Delay Switch, Issue #558

- Add a -DELAY switch to the TUNE command line to force the use of delay mode for note pacing.  Issue #558  Credit to @robbbates for suggesting this.
- Add missing include file logic for DS1307, Issue #556.  Credit to @tpycio.
- Miscellaneous documentation improvements per Peter Onion and Petr Antos.
