Initial version of the Dutch Smart Meter Binding

I have developed a new binding for Smart Meters in the Netherlands.

This binding reads the P1-port of Smart Meters and parses output conform the Dutch Smart Meter Requirements (v2.1, v2.2, v3.0, v4.0 and v4.04).

For more information of this binding see: http://www.lipin.nl/DSMRBinding.html

Note: Probably only Dutch OpenHab users are interested in this binding.
