	* most audit revisions * remove expected income * update begin block spec * filter queryAtomicSwaps, add queryAssetSupplies * update old address * update test * Remove legacy method * remove legacy comment * address PR comments * IsValid for SwapDirection, SwapStatus * fix rng logging * query asset supplies * return [64]byte from rng * remove cross chain field from MsgCreateAtomicSwap * move swap filtering to querier * rename Limit field to SupplyLimit
