At the same time, I moved the logic to check if the language should be
updated into the new LanguageUpdater class.  The README has been updated

Hashes are now stored in hash.json, not hash.yaml.  Also, we use the XDG
configuration directory rather than assuming we should use ~/.config/.
Maybe I should also make use of XDG data and/or cache directories.

This fork is called Kaylee, not Blather.  Let's at least be consistent
with referring to the program as Kaylee, even if the code is still in
blather.py.

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.
