Add a vop to record median price when HIVE is converted to HBD due to a hive.fund donation.

Hey just a small help, I'm trying to find the instant conversions operation for the HIVE sent to the hive.fund.
eg.https://hiveblocks.com/tx/3423456951a32335a2688723c7b753a203f9d0c8

Here there is a 3k HIVE sent to the hive.fund, but I cant find the conversions to HBD. I looked in hiveblocks for the hive.fund operation.
