Place Built-In Connection Types in their Own Group

As discussed with Rolf, the built-in connection type, Directional RF Connections and RF Connections which come with KS8400 can be placed in their own group. A suggestion to the name of the group is "Basic Connections". The background is that P7000A project has implemented some product specific connection types, and those types are placed in their own group. this is done to make it easy for the customers to select the correct connection type, which are required by the product.
