Report delegate not paying out

[roks0n]

We'd like to be able to report if a delegate is not paying out or now. If we get enough complains we'd note this potential concern on the page of a delegate.

Only wallets that vote for a delegate (or have voted for that delegate for X days) would be able to report them and the amount of Ark that they hold would indicate how serious the concern is on a scale from 1 to 10. In order to show the "warning" at least 1% of delegates voting power would have to report the delegate. Also the wallet reporting missing payments should have a consistent balance since at least a week from report.

A delegate should also be able to comment on triggered reports and the history of reports should be visible.
