Add a UI to show all entity links in flowgraph mode

[ghramsey]

I know the flowgraphs are the way of the future and for linking entities and un-linking
them it's great.

But the flowgraphs are also unwieldy to find how entities are linked and with what
because of multiple pages and the nodes can be many and the links blendtogether.

Can you keep some element of the old GUI to show how everything is linked together?

Perhaps as a 'info' button where it's only that, informational and still uses the flowgraph
for work. Or an option to switch between the two types of interface.

Your 'instance mode' roadmap might solve all of this of course.
