Commands aren't stored in a special file anymore, and Kaylee never tries
to look at that file.  Therefore, there's no need for the Config object
to keep that file's path, and so the path has been removed.

Added some blank lines and wrapped some long lines to be closer to PEP 8
compliance.

Improved docstrings in NumberParser class.  Added docstrings for
undocumented code and removed a TODO message that no longer applies.

Apparently CMU thinks it's a good idea to release a new version of a
piece of software that breaks existing APIs without even changing the
version number.  I find this idea to be highly dubious at best.
Nevertheless, I have updated Kaylee to support the latest version of
pocketsphinx.

That's "Kaylee Voice Command" if you didn't figure it out.  I think
everything still works properly, but I'll do more testing later to
verify.
