Add NFT Transfer Option on Xahau Network using the Remit.

[Anna15170221]

We need to add an option, to transfer NFT using the Remit. If destination doesn't have disallowRemitIncoming (allows remit trxs) then we can just send NFT to the destination without asking (but paying for the NFT reserve).

@ihomp yes, you are right. I will amend the ticket

I guess we can close this one, as it the same as this one? #519
no?

@ihomp i thought these were supposed to be different options - to send tokens with Remit and NFTs with Remit - am I wrong?
you discussed with crische that The Remit option can also be used to send tokens, even if the destination does not have a Trustline for this. so 1 ticket is for tokens and another one is for NFTs
