Peter Hamilton f9e32552f8 Add client support for custom configuration file paths
This change adds client support for setting custom configuration
file paths, allowing users and developers to place their settings
file wherever they want. All client demo scripts have been updated
to support a '-s' flag that can be used to set the configuration
file for the demo. Client unit tests have also been updated to
include this change.
