* Added a simple implementation of the Imageapp (Image uploading

 and displaying of the latest image) using the Play Framework in
 Scala.
 * To start up the Play server, you'll need to install Play and run
 the 'play' command on /cse491-serverz-play and then type 'run'
 * You will also need to edit
 /cse491-serverz-play/conf/application.confg
 and after 'db.default.url="jdbc:sqlite:' type the absolute path
 to the imageapp database. Not sure how to do this platform
 independent yet!
 * Added a commenting system (with persistent comments) to
 imageapp. To add a comment, click on an image and fill out the
 form and hit 'add comment'. Existing comments should display
 on the same page.
 * Images that are loading in the 'browse all' section now have a
 gray background while they take their sweet time.
