Create viewer / module-short-list short-cut

[GoogleCodeExporter]

Right click on output port, at the bottom there should be a short-list of
often-used modules.  Viewer at position #1.

If this is selected, the module is created and connected to that output
port.  The network is immediately executed if relevant (viewer).
