cointool: replace 'coins_json' with 'dump'

Browse Source 
`cointool.py coins_json` generated an old-style `coins.json` file with
entries on bitcoin-like coins. This is no longe really doing what we
need.

Instead, the new command `dump` will output _all available data_ in the
same format as Python sees it. Much more useful for other kinds of
consumers.
