Add support for spellchecking with a custom dictionary.

To use:

  1. Install aspell
  2. waf spell <list of files>
     * waf spell mydoc.rst
     * waf spell *.rst

This uses a custom dictionary stored in common/spell/dict/.  We should add all
RTEMS and programming terms to this to ensure we are consistent.

Amar.
