Not only implemented weather for PEQMac, but also improved the EQEmu weather system.

-Individual zones now have their own weather chance
-Added a weather type 4, which allows it to rain or snow in zones with that set
-The max weather timer is now a rule, Zone:WeatherTimer

DB changes are required, they will be put into Alkabor DB and dumped right now.

Eventually, I will get this into EQEmu git ;)
