Extends the grammar to include the annotation type declaration. The current impl only supports marker and single annotation declaration.

Annotation type is represented by class descriptor since annotation type declaration is a special kind of interface declaration. Later, we need to implement semantic checkings for annotations.

Fixes. Almost everything works (but still no importing subclass support).

JNI compilation on Brian's test file still fails, HOWEVER I believe it's because /classpath/java/lang/ should be added into our state.classpaths vector. This should be true because Java automatically imports java.lang.* in every file, so it's essentially like having it as a class path.

I've left 1 System.out.println statement in extra to help trace which files are trying to find which files. When I look at the one I'm currently crashing on, I see that there is indeed no Class.java file in its package and it doesn't import it anywhere.
