sir, took some more time to get around to it but here it is:
quick and dirty implementation of nsecbunker
key points:
* uses a separate relay connection (I think it makes more sense to have the signer connectivity separate since it's useless to push the signing events to pretty much all relays except the ones where nsecbunker is listening to)
* local key, generated locally
