Core/LFG:

Fix priority of the player when its added to the lfg group
        Better implementation of the Dungeon Deserter debuff
        Rewrite the NeedBeforeGreed loot
        Fixed players being shown as Unknown Entity when entering the lfg group
        Some incremental optimizations after original patch
Thanks to Retriman and Paecman for base implementation
