[Feature Request] Decreased amount of spell reagent

[canerksk]

        if ( Calc_GetRandVal(100) >= iLowerReagentCost)
        {
            CContainer* pCont = static_cast<CContainer*>(pCharCaster);
            const size_t iMissing = pCont->ResourceConsumePart(pReagents, 1, 100, fTest);
            if (iMissing != SCONT_BADINDEX)
                return iMissing;
        }

        const size_t iMissing = pCont->ResourceConsumePart(pReagents, PROPCH_LOWERREAGENTAMOUNT, 100, fTest);

Here, a fixed amount of spells is reduced for each spell, but this reduced number of spell materials may vary for additional features. For this, an additional feature can be added as PROPCH_LOWERREAGENTAMOUNT, rather than a feature that works as a percentage, such as PROPCH_LOWERREAGENTCOST.

The codes here are purely examples. Although many have been tested, some may need to be rewritten.
