object_hashes messages should only be sent after comparing object_hashes_hash (not relevant with today's link speeds and computer memory sizes)

[andrewhodel]

object_hashes messages are sent after connection on an interval.

They contain a hash of each object that the node has.

They should be sent only after a comparison returns unequal for an object_hashes_hash message because there could be a billion objects (therefore a billion object hashes). This will make equal comparisons much faster across the network but is irrelevant at the link speeds of today and the computer memory sizes of today.
