Fabricating flexibility for queue settings

Added support for specifying queue settings via app.config.  Settings are expressed in XMLified JSON data (" = &quot;.  Of course other conversions as necessary).  Unit tests added for config objects.  Verified at runtime that config is used.  Code updated to use config.
