AGIP6 - Add 0.5% Fee on Baazaar to Support Rarity Farming

Background: With the announcement of SZN1 Rewards now official, we explore how to align the community's interests and rewards structures, as it pertains to Baazaar fees. Currently, 2% is allocated to Pixelcraft and 1% to DAO treasury. While not exclusive of providing for RF rewards, the treasury funds are currently in no obligation to be allocated in any form of ratio towards the RF pool each season. Proposal: Increase the Baazaar fees from 3% to 3.5%, with the additional 0.5% going directly to the Rarity Farming rewards pool.
