Apply AreSane() checks to the fees from the network.
'Sane' was already defined by this code as: fee.GetFeePerK() > minRelayFee.GetFeePerK() * 10000 But sanity was only enforced for data loaded from disk. Note that this is a pretty expansive definition of 'sane': A 10 BTC fee is still passes the test if its on a 100kb transaction. This prevents a single insane fee on the network from making us reject our stored fee data at start. We still may reject valid saved fee state if minRelayFee is changed between executions. This also reduces the risk and limits the damage from a cascading failure where one party pays a bunch of insane fees which cases others to pay insane fees.
