            Quick documentation for hackers who want to screw around with this:
            For Facebook to properly use video information, all four video fields *and* the image must be populated. 
            So if you're going to try to do some url magic, then you may need to make an API call somewhere to get the
            			image for the video thumbnail (or other things, conceivably). If you do, then setting the $save=true like I 
            			did above will make the below line of code save your results in post meta and then they won't have to be 
            			re-retrieved from whatever API you're hitting. There's a call up at the top to handle retreiving those
            			meta results and using them, thus bypassing all the parsing nonsense.
            But, ONLY set $save to true if you're making external API calls. If you can get the image info without making 
            			an external hit, then leave it false so as to not waste space in the DB with the meta information. Notice how
            			I don't save the YouTube info because it's not necessary. In actual fact, that image isn't the exact same as
            			the one they use on their data, and I could make an oEmbed API call to get their image, but it's pointless
            			since that image URL I'm generating always works anyway.
