Subject: AnnotationHandlers can now return a boolean to set if they actually
 handled the annotation or not (previously, the presumption was they always
 handled the annotation).

This is very useful for PrintAST on eclipse, because before this change, you'd never see method contents (as the initial dietParse would come first). Now Eclipse PrintASTHandler

will skip any non-full runs, and only print non-diet. It then returns true only if it printed.
