It's not really temporary, so tmp isn't a sensible suffix.  It's
provided in the distribution of the package, so dist is.

After listening to HPR 1284 today, I realized that it's important to
keep configuration of what Kaylee *does* separate from other
configuration.  Specifically, once TTS integration is done, voice
configuration will need to be separate from configuration of actions,
because it's common to have several computers with the same actions but
different voices.  Therefore, I've moved all configuration about plugins
into a new file called plugins.json.
