Add conf Command

[rwxrob]

Need an intelligent conf utility that detects configuration files in
their intuitive places and looks up values from them or sets them. I
want it to be smart enough to detect YAML and JSON and regular UNIX
configuration files and just do the right thing. I only want one utility
to manage it all. I won't be creating scripting dependencies on conf
just want an easier way to set configuration from the command line in a
universal way.
