Advanced common drop system 0.0.1

I think it would be more flexible, if it would work this way:

2115,1 would make valkyrie shield is not effected by drop rate, so you can use the full scale (from 0,01% to 100%).

The original idea would force that, every mob has to drop that item with the SAME chance. However this way the same item can be dropped with different chances from different mobs.

Ind's Special item drop system can't do it.

so. I base on Ind's work to finish this to solve xazax's probrom.

this patch. base on eAthena r15049 trunk.

that is all,. enjoy it.
