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

-USART
-=====
-
-A USART is more commonly known a *serial port*.  It's used to transmit
-information between Maple and another device (like your computer,
-another Maple, etc.).

-Hardware/Circuit Design
------------------------
-
-.. TODO [0.0.12] Add some more information here (like how you should
-.. connect TX_a to RX_b and RX_a to TX_b).
-
-.. TODO [0.0.12/Maple Native] UART4 and UART5, Native links
-
-Each LeafLabs board has at least 3 separate USART devices. In the most
-simple use case, the RX and TX pins are used to send data at a
-predetermined speed (or *baud rate*).  Their usage is documented in
-the :ref:`Serial Ports <lang-serial>` language reference page.
-
-Which pins correspond to the USART TX and RX pins are given on your
-board's silkscreen, and also in the board-specific USART pin maps
-available here:
-
-* :ref:`Maple <maple-usart-map>`
-* :ref:`Maple RET6 Edition <maple-ret6-usart-map>`
-* :ref:`Maple Mini <maple-mini-usart-map>`
-
-If you use a particular serial port, you cannot also use its
-communication pins for other purposes at the same time.
-
-Compatible Devices and Specifications
--------------------------------------
-
-We have successfully used the USART ports with an FT232R-based
-USB-serial converter at up to 115200 baud.  Higher speeds should
-certainly be possible.
