Download and upload as a one-step process

[matthugs]

Currently we have scripts for download and separate scripts for upload. It would be great if we could cut the filesystem out of the matter, and host the emoji on the web.

I investigated options for non-filesystem drag-and-drop browser functionality. Initially wasted a good amount of time eliminating the "A cool finding" section of https://www.thecssninja.com/javascript/gmail-dragout as a leveragable strategy. If that article was correct it would've paved a way to use exactly the same script for upload we already had. Seems like the features it alluded to are no longer available in either of chrome or firefox.

An alternative would be to pass over emoji only in the form of URLs, which could be parsed for emoji names and downloaded for the file. The first step would probably be to get the list of URLs through the DataTransfer interface for drag-and-drop browser functionality. I found this only worked as one would expect on Firefox, which is disappointing enough for me to not pursue the matter further. http://jsfiddle.net/t9qkb31n/
