add the ability to drag emoticons into the message input field (drag and drop)

[Vorun5]

There is a cool feature on trovo that I use often, drag and drop an emoticon from a chat into the message input field. On twitch, when I also drag the smiley into the general message field, the url link to the image of the smiley just appears (which is basically normal behavior). You can add at least a checkmark in the settings to enable this feature.
