Currently, the callback for the Giphy shortcode is trying to extract the gif ID from the giphy URL by exploding the URL on dashes.
This works for URLs of the pattern [giphy url="http://giphy.com/gifs/mulder-wheelies-FcHcQIpQD5Bmg"]
However, the url [giphy url="http://giphy.com/gifs/FcHcQIpQD5Bmg"] is also a valid link to the same gif and should be handled, as it is what we will get if pasting the embed code into a post and doing a reversal on it.
