Add experimental (slow) force-directed graph layout to Ganv.
This continuously arranges the graph, and the user can drag around nodes to
influence the layout which is handy.
To try, configure with --no-graphviz --fdgl.
Still rough around the edges, in particular detached nodes will fly off into
space. Also entirely too slow for production use, will need a more
sophisticated data structure for that, so the repel calculation isn't O(n^2).
