Remove reST documentation, attendant updates.

The documentation covers topics not specifically relevant to libmaple,
so it doesn't make sense for it to be part of the libmaple source
distribution.

Delete the docs/ tree, and prepare libmaple for use with the new
leaflabs-docs repo, which will contain the docs from now on.

* README: update to reflect this change

* support/doxygen/Doxyfile: This is the old docs/Doxyfile

* Makefile: Add a doxygen target

* wirish/comm/HardwareSerial.h: fix reference to docs/.  The comment
  informing maintainers that the HardwareSerial interface is
  documented by hand refers to the docs/ tree, which no longer exists.
  Update it to refer to the separate leaflabs-docs repository.

* support/scripts/copy-to-ide: No longer build the documentation

-.. _lang-tone:
-
-tone()
-======
-
-Description
------------
-
-Generates a square wave of the specified frequency (and 50% duty
-cycle) on a pin. A duration can be specified, otherwise the wave
-continues until a call to
-`noTone <http://arduino.cc/en/Reference/NoTone>`_\ (). The pin can be
-connected to a piezo buzzer or other speaker to play tones.
-
-Only one tone can be generated at a time. If a tone is already
-playing on a different pin, the call to tone() will have no effect.
-If the tone is playing on the same pin, the call will set its
-frequency.
-
-Use of the tone() function will interfere with PWM output on pins 3
-and 11 (on boards other than the Mega).
-
-**NOTE:** if you want to play different pitches on multiple pins,
-you need to call noTone() on one pin before calling tone() on the
-next pin.
-
-Syntax
-------
-
-tone(pin, frequency)
-tone(pin, frequency, duration)
-
-Parameters
-----------
-
-pin: the pin on which to generate the tone
-
-frequency: the frequency of the tone in hertz
-
-duration: the duration of the tone in milliseconds (optional)
-
-Returns
--------
-
-nothing
