I downgraded to Java 7 and made all the loading work. IT LIVES!

The only known bug in the loading is an issue with the Logger and its
integration with Minecraft's GUI. We may want to consider just
reimplementing that function ourselves through overextension. Even that
would just be temporary until we make our own GUI.

The other changes are mainly adaptations to make this project work in
Java 7.
