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

-
-Constants
----------
-
-- ``true`` and ``false`` are the :ref:`boolean constants
-  <lang-booleanvariables>`.
-
-Control Flow
-------------
-
-- ``break`` can exit out of a :ref:`switch statement
-  <lang-switchcase>` or a :ref:`for <lang-for>`, :ref:`do
-  <lang-dowhile>`, or :ref:`while <lang-while>` loop.
-
-- ``case`` defines alternatives in a :ref:`switch statement <lang-switchcase>`.
-
-- ``continue`` will move control flow to the next iteration of the
-  enclosing :ref:`for <lang-for>`, :ref:`do <lang-dowhile>`, or
-  :ref:`while <lang-while>` loop.
-
-- ``default`` defines the default alternative in a :ref:`switch
-  statement <lang-switchcase>`.
-
-- ``do`` introduces a :ref:`do <lang-dowhile>` loop.
-
-- ``else`` is used in :ref:`if statements <lang-if>`.
-
-- ``for`` introduces a :ref:`for <lang-for>` loop.
-
-- ``goto`` :ref:`jumps <lang-goto>` to a label.
-
-- ``if`` introduces an :ref:`if statement <lang-if>`.
-
-- ``return`` :ref:`transfers flow to a function's caller <lang-return>`.
-
-- ``switch`` introduces a :ref:`switch statement <lang-switchcase>`.
-
-- ``while`` introduces a :ref:`while <lang-while>` loop.
-
-Types
------
-
-The following keywords are used for built-in types.
-
-- :ref:`bool <lang-booleanvariables>`
-- :ref:`char <lang-char>`
-- :ref:`double <lang-double>`
-- :ref:`float <lang-float>`
-- :ref:`int <lang-int>`
-- :ref:`long <lang-long>`
-- :ref:`short <lang-built-in-types-integral>`
-- :ref:`void <lang-void>` (not really a type, but used in the absence
-  of one)
-
-The following keywords are used to introduce new types.
-
-- :ref:`enum <lang-enum>`
-
-Qualifiers
-----------
-
-- :ref:`static <lang-static>` can be used to declare persistent local
-  variables; it has other uses not documented here.
-
-- ``unsigned`` is used to specify an unsigned integral type.
-  Examples: :ref:`lang-unsignedint`, :ref:`lang-unsignedchar`.
-
-- :ref:`volatile <lang-volatile>` is useful when declaring variables
-  that may be modified by external interrupts.
-
-- :ref:`const <lang-const>` is used to define constants.
-
-Other
------
-
-These keywords are not described in the Maple documentation.  For more
-information, consult a C++ reference.
-
-- ``asm`` is used to insert literal assembly language.
-
-- ``auto`` is used to declare that a variable has automatic storage.
-
-- ``catch`` is used in exception handling.  Note that the default
-  flags we pass to :ref:`GCC <arm-gcc>` include ``-fno-exceptions``.
-
-- ``class`` is used to define classes.
-
-- ``const_cast`` is used in typecasting.
-
-- ``delete`` is used to free ``new``\ -allocated storage.  Note that
-  dynamic memory allocation is not available by default on the Maple,
-  so you'll have to bring your own ``new`` and ``delete`` if you want
-  this.
-
-- ``dynamic_cast`` is used in typecasting.
-
-- ``explicit`` is used to declare constructors that can be called only
-  explicitly.
-
-- ``export`` declares a template definition accessible to other
-  compilation units.
-
-- ``extern`` can mark a declaration as a declaration and not a
-  definition, and also grant external linkage to a ``const`` or
-  ``typedef``.
-
-- ``friend`` is used to declare that certain functions have access to
-  a class's private variables.
-
-- ``inline`` is a compiler hint to inline a function.
-
-- ``mutable`` specifies that a member can be updated, even when a
-  member of a ``const`` object.
-
-- ``namespace`` declares a new namespace.
-
-- ``new`` dynamically allocates space for a value.  Note that dynamic
-  memory allocation is not available by default on the Maple, so
-  you'll have to bring your own ``new`` and ``delete`` if you want
-  this.
-
-- ``operator`` is used to define type-specific operator overrides.
-
-- ``private`` declares a private class member.
-
-- ``protected`` declares a protected class member.
-
-- ``public`` declares a public class member.
-
-- ``register`` is a compiler hint to store a variable in a register.
-
-- ``reinterpret_cast`` is used in typecasting.
-
-- ``signed`` is the opposite of ``unsigned``.
-
-- ``static_cast`` is used in typecasting.
-
-- ``struct`` declares a new struct.
-
-- ``template`` introduces a template class, function, etc.
-
-- ``this`` is a pointer to the receiver object.
-
-- ``throw`` is used in exception handling.  Note that the default
-  flags we pass to :ref:`GCC <arm-gcc>` include ``-fno-exceptions``.
-
-- ``try`` is used in exception handling.  Note that the default
-  flags we pass to :ref:`GCC <arm-gcc>` include ``-fno-exceptions``.
-
-- ``typedef`` defines a type synonym.
-
