Cleaned up PathFinder by taking out a lot of commented-out code. Previous commit: cleaned up the ranking ajax request by removing the d3.json() call...it was pointless and merely doubling the amount of requests we were making. Now the GET request is done solely by jquery.
Deleted redundant images folder (it not needs to be located outside the submodule because that's where the html pages are. Also deleted the redundant html pages (same reason). Updated YouTubeSlideGenerator to have more flexible player sizes.
Added a timeout on Summarizer so that we aren't stuck waiting forever when the abstractFinder servlet is down. It times out at 30 seconds now
Implemented timing update on SlideEditor. However YouTube slid durations appear to be inceasing by 5 seconds after leaving the editor phase...
Re-integrating playerSave functionality...while they ARE getting saved, they aren't getting used, yet
players were being used, but their iframes were remaining hidden, thanks to a mismatch between player.id and player.playerId. Videos appear now, but are stopping early
Players are now recycled when user specifies a youtube video be used. Still being wasteful when using defaults. Also need to figure out how to reuse the youtube players when using the go back option...Players are currently being deleted upon finishing, but even keeping them, their playbacks would currently involve continuing from wherever they were stopped
Changed the Youtube api call from http to https to eliminate angry Chrome messages
Merge with master, since I apparently forgot to push for the last 2 weeks..
