Clean HTML output when zettels are deleted

[felko]

Currently neuron rib adds .html files from new zettels, but never deletes files from the .neuron/output directory. Could neuron rib take care of deleting previously generated HTML files that no longer have an associated zettel? Unused HTML files might clutter disk space. Maybe something like neuron rib --clean?
(Maybe this should be a rib issue?)

Maybe this should be a rib issue?

Yes. See srid/rib#155. PR welcome. :-) (neuron no longer uses rib)

Workaround in the interim:

rm -rf .neuron/{.shake,output}
neuron rib

This can now be simply done here (by comparing the old routes list with the new one)
