rare desyncing issue

[Georg Friedrich Schuppe]

While playing around with clumsy and these settings:

I was (after several minutes of running the game) able to desync the BoxGame clients, but could never replicate it. I don't know how that happened.

Important notice: when affecting loopback packets (localhost -> localhost), all clumsy settings affect these packets twice, meaning that a 50ms delay is actually a 100ms delay, leading to a 200ms round-trip time.
