Write and test (non-posting) port of Watching The Watchers bot

[pibara-utopian]

In order to field test the 0.5 version and see if everything runs stable and reliably, a port of the @pibarabot Watching The Watchers scripts should provide a good opportunity to do just that.

This port won't do any posting yet, due to signing being unimplemented.

The bot should be enhanced in the way that:

• The current MVVP metric is replaced by an rshares based metric
• It distinguished between flagging and attenuation of upvotes.

Mostly done, waiting for input for a bit, then add a cron script and let it run a couple of days before closing this issue.
