Converted to Java 8

This includes the changes needed to run with Java 8.  I still haven't had time to figure out how to get Eclipse to export a JavaFX combined with Swing project properly, so you will (unfortunately) need Netbeans 8.0.1 (or higher) to edit/build this.  Netbeans will open the project if you go to "File->Open Project..." and point it to the base folder.  I have not figured out how to complete the Mac App Bundle creation process - I can create the bundle, but you still need to move the "resources/" folder into place in "Contents/Java/" in the bundle by hand.  Same goes for the "example/" folder in "resources/example/".  Even with that, the application can't find the "example" folder, and I have not had a chance to track down why.  This version does not disable "compress on export", as has been requested.  I am working on removing that, and will send a separate pull request in the next few days, once we all agree on what that will look like.
OK, not a big deal, though I'd be interested to find out later.
