* Create temporary directory, cleaned up on exit, and use it to store
  (inter alia) audio samples for the sample-player plugin.
* Ensure newly added layers always have unique names
* Make sure configure pairs for real-time plugins are stored in the
  configuration Xml along with parameter & program settings
