Update Tier 2 - 3 Benefit (Patreon)

From now on all member in Tier 2 - 3 will get benefit when asked me for the commission include for YCH as well. The amount of discount depending on Tier level. 

My point is I give you back what I got from you. It's a benefit I can offer from you. If I had get much more income I will try to upgrade the benefit as much as I can.
