Packet sending partially works.

Host is receiving duplicates from client, since client spams
the same packet until acknowledged.
Skew correction isn't working either, as a result.
Packet ack half-working, but this is really backwards.

Should probably switch host<->client roles.
SO CLOSE to working. Something is messed up with queues.

Most likely queue_packet_ready() on client side, otherwise something
to do with host/client onReceive.
