Changes on Ketchup & Mayo Tier. (Patreon)

Adding some stuff for the Patreon benefits, specifically Ketchup and Mayo tiers.
Prices won't be changed but recently I've been thinking about that instead of giving characters discounts for commissions, I should give those discounts to my supporters, appart from the comm priority.

On the next month:
Ketchup tier will have a 7.5% discount and Mayo tier Will have 10% discounts on every commissions, this discounts may change depending on reception.
