Add the ability to send to Assets! rather than just addresses

Title explains it all, going to make a gitcoin bounty for 0.3 ETH and encourage others to donate to this cause, it will add so much value to asset names.   If this works, I will do another bounty for incoming RVN and memos to list all of the Asset! name of the sender for much more $$ and by then I hope this second bounty gains more traction with the community
