docs: point at pyzmng.readthedocs.io and connect the remote sections

The RTD project was renamed to pyzmNg in df09f17 but every URL still said
pyzmv2 -- setup.py, the README and six examples. All now point at
pyzmng.readthedocs.io. CHANGELOG is left alone: those entries are historical.

The remote sections were also reachable only by scrolling. Wired them up:
model discovery now points forward to the correlation rule and to the
declaring-models section (which gained a label), /models and /infer point at
the correlation rule from the API reference, and the ZoneMinder back-reference
is a real list of links instead of a prose "see the other docs".
