Feature: Navigation from VikingView to Viking

There is no way to navigate from VikingView to Viking.  I suggest adding the following:

A UI command that when activated finds the center of the polygon under the mouse and places the 3D coordinates into the clipboard for pasting into Viking.  The format Viking expects is simply a text line with XYZ, i.e "X: 5000 Y: 3000 Z: 45"
