Drop rate and shard&frags rework and some ideas

1- Now shards and frags can be upgraded up to lvl 19. (Reduced a bit pd,hr,light,cd,cc drop ratio from mobs and chest) (pd 80 weapons,hr140 weapons,30 str horned,cc38 and cd60 weapons...) ( reduced 1% dmg of poison to unit)

2- Reworked drop rate, new stat: drop quality. from lvl 1 to 250, scales from 0 to 80%, increases rate of higher stats items. (stones and rare items are not affected) Examples: lvl 30 mob = 27% drop quality = added 27% stats to your next epic drop

3- Luck gives no more drop chances, changed crush chance from 0.33% to 0.35%

4- Reputation now gives a bit more chances of rares and stones drop

5- Reworked chest drops, every bronze chest gives you +1 rep, silver+2 and gold+3 Reduced a bit chest spawns and upgraded a bit spawn time 

6- Plate mail: defense ratio up from 37 to 40

7- new item: merien gem: add +1 dmg reduction on a vortexed item
                       xelima gem: add +1 dmg on weapon

                      Drops from: elementalist & abbadon & wyverns

8- Fire talent: magic crush dmg reduced from 8% to 5% / crush chance up from 10% to 15% /
