unused: Support --json and --json-error-messages

Browse source 
Generalized AddJSONActionItemField to allow it to add several fields. Not entirely
happy with that, since the names of the fields have to be carefully chosen to
not conflict with other json fields. And fields added that way can't be parsed
back in FromJSON, except for the "fields" field that is special cased for metadata.
Still, I couldn't see another way to do it.

Also, omit file:null from the json output. Which does affect other commands,
eg git-annex whereis --all --json. Hopefully that won't break something that expects
a null file. If it did, that could be reverted, but it would be ugly to have
file:null in the unused --json
