Send transactions after a CMerkleBlock when asked for it in an inv.
This actually simplifies some SPV code, as they can keep track of a filtered block and its txn before accepting both in one step. The previous argument was that SPV nodes should handle the txn the same as any other free txn and then mark them as connected to a block when they get the filtered block itself. However, it now appears that SPV nodes will need to put in more effort to verify loose txn than they would to verify txn in blocks, thus making it more approriate to send the txn after the filtered block.
