Fix the 500 kill cape!

Personally I would like to see KD changed, or removed as a metric

IMO

Make the current KD archived so it's still visible but make a new KD everyone starts at 0/0

* Kills on accounts that haven't moved, or interacted with the world for 3 minutes don't count.
* Kills on accounts 50% lower combat than your account don't count.
* Kills on 3 item, unskulled account don't count.

Then lets have a new real KD and give great items for those only but make it require positive KD.
