ClioPatria cpack swish -- Add Prolog interaction to ClioPatria

Make the SWI-Prolog SWISH package available as a ClioPatria cpack. SWISH brings a Prolog interface to ClioPatria, providing:

Ask RDF queries about our data
Make example programs available about your data
Save an example program and share it with anyone on the web
Collaborate on a program using TogetheJS
Manage a server remotely from the Prolog shell (requires login with admin rigths).

This package is just a first preview. We have many plans for making this more powerful and friendly.
