VID-1801 Script to migrate screenplay vids to ooyala

Well, I wanted to wrap the operation in a transaction and I guess I never saw that done with fluent so I just defaulted to the old school, tried clunky and true mediawiki way. Now that I think about it, a $db->begin(); and a $db->commit(); around the Fluent calls would probably do the same thing, huh? Ah well, Fluent is on the up and up, I'll let our old db system feel useful for a little while longer :)
