[HF suggestion] Reduce content reward by sending equivalent of downvoted rshares to @null (burned)

I currently disagree with more than 50% of the reward allocated to current authors and therefore would prefer the reward I downvote be burned instead of being moved to equally undeserving people.

We're not mainstream yet. Contributor reward should be made to be elastic.

It's been talked about letting the DHF allocate the whole reward pool to "content" pool but I've never seen even a complete description of how that could be implemented.
