Brock Whittaker 3a4fff837f Identify if an emoji URL is invalid and signal an error. ...

Previously, no error would display in the UI if the link to the emoji
image was invalid. This would happen for instance if you put in
“invalid” for the Emoji URL. No alerts would pop up but it would refuse
to add the emoji.

This catches the error and displays a notification that looks like
“Failed: Enter a valid URL.”

Fixes #1116.
