Account-wide Exp/Drop/Death Modifiers

Attempting to mimic the official as suggested in http://hercules.ws/board/topic/250-official-vip-system/
The variables can be read and modified thru scripting as well as sql, the patch introduces 3 new pc-arams 'ModExp','ModDrop' and 'ModDeath' for that purpose.
The OnLogin modifier display is not the real deal though -- wasn't able to get it to output properly (though that might have been my client files failt)
Up for review.
