Feature Request: Improve Rating Function

Add ability to rate a receiving peer if a channel close is detected.

In a recent triangle swap I was node "B". 
Node "A" closed early to both "B" and "C". 
Node "C" adjusted their rating to negative I assume because they did not understand their rating is for the node that opened to them. 

I have been in similar situations as "C" in other swaps where the peer I opened too closed early and there is no way of rating them.
Obviously not a big deal, but it would be a nice function.

Or alternatively, add a notice when changing your rating to indicate what peer is receiving the rating. 

Thanks,
