What's new

[+] Added console logs if someone sends over 200 packets/s (this is just info, can happen to legit players due to lag)
[+] Added more config options to Admin GUI
[+] Added Ping-Pong Timeout kick to the config. Kicks if the player doesn't respond to Ping packets for 30s. This prevents cheaters from disabling the anticheat by ignoring these packets.
[+] Added config option "StopMovementWhileInDeathScreen". Default is false, this prevents hack clients from moving around while in death screen / ignoring death screen. But this will always also affect normal players (mostly visually), e.g. when dying while falling.

[#] Now using proper air drag calculations for Motion(A)'s terminal velocity check
[#] Made lag compensation 1 tick faster
[#] Bumped supported version to Hytale 0.5.3
[#] Extended BadPackets(D) with the new block placement options from update 5 
[#] Fixed wrong total player count in AdminGUI
[#] Testing some more packet validation checks
