Simulate nodes in each community

[rubo77]

I started to create a testnode vm at https://github.com/rubo77/freifunk-gluon-example-node

there are some issues open

I refactored the current working branch as https://github.com/rubo77/ffnord-example/tree/testnodes still an open issue: #8

Maybe now we can use the x86-generic images. They come as targets for example here:
