Add in ability to send RVN Assets in discord

Yo MSFT, haven't seen ya in discord for a while didn't know how else to get in contact with you.

Could you update the tip bot so that users are able to send rvn assets in discord?  This would help greatly with asset adoption and trading etc... At least for the memes.  Not sure how much code it would take to add this functionality. 

Come drop by discord and we can chat.
