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.

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.

See commands.tmp for an example.  It's pretty neat, but it could still
use some work.  I thought of a really clever way to parse numbers, better
than the one I came up with last night, but since I have a working
implementation now I figure I'd better commit it.

We have a new bug which causes the dictionary to be updated every time the
program starts.  I hope I didn't force that to happen last night or
something, but I have a vague feeling I did.

Mostly working for the options file now.  Still some difficulty with
command-line arguments, though; they're overriding the config file even
when not specified.  If I made them simply not get stored at all when
not specified, there would be further problems when a configuration file
is not present.  Maybe I should make a whole new class to handle this.

I'm a GTK man myself.  I don't know if I have Python QT bindings
installed on any of my computers.  It follows then that I would not
maintain the QT interface well, let alone use it at all.  It has
therefore been removed to avoid having someone try to use it only to
find that it's broken.

Gotta keep that stuff up-to-date, yo.  Pocketsphinx changed so it needs
GStreamer 1.0, and that required rewriting everything to use GObject
Introspection instead of the old, static Python bindings for GObject.

a few print commands were remove too.

Added active/inactive icons
