The idea behind this is to keep abusive clients from flooding the
server. Everything from over-voracious auto pick-up to exploitation
of NPC vulnerabilities is mitigated by this. It will also eventually
reduce server traffic, load, and possibly lag.
Config options in battle_athena.conf:
packet_spam_flood (default 30)
packet_spam_threshold (default 2)
packet_spam_kick (default 1)
Each packet type has a specified allowed incoming rate in milliseconds,
if this rate is exceeded the packet is ignored. If over 'flood' overruns
in 'threshold' seconds are detected, a flood is logged and a kick may be
triggered depending on the 'kick' config boolean.
The packet rates and flood thresholds have been tested and tweaked
on a live server, this should only affect abusive clients. Only
extremely abusive clients will trigger a log/kick condition.
This probably obsoletes the trade and kick spam code.
