Allow dragging magnet links

[RaeesBhatti]

It would be handy to have the app accept dragging of torrent links instead of doing a manual copy-paste.

Maybe need to make some changes here in the drag-drop package.

Looked into it. This would require making drag-drop a lot fancier / more complicated or writing our own drag drop handler.

It might be worth changing the text to say "Drop a torrent here or paste a magnet link (sorry, dragging magnet links won't work)"

Right now the language is technically clear, but I assumed it was possible to drag a magnet link, and it seemed like the app was simply broken when that didn't work.

A form field would be the standard way of allowing somebody to paste a magnet link. Then it would be very clear you were asking them to paste it.

I've added a PR on drag-drop which adds support to drop magnet links.

Thanks for the PRs to drag-drop, @mathiasvr and @codealchemist ! I think this should be straightforward to implement in WebTorrent Desktop now 👍

[feross]

Sent a PR that implements this: #758

Review and testing welcome! 👍

Awesome! Thanks @feross!
Already added comments on the PR :)
