Merge branch 'refactor'

This merges the libmaple refactor work into master.  The contents of
libmaple proper (/libmaple/) are almost completely incompatible with
previous APIs in master.  See /docs/source/libmaple/overview.rst for
more information on the new design.

Wirish incompatibilities are limited to the HardwareTimer class;
however, there are several new deprecations, most likely to be removed
in 0.1.0.
