Refactor ScopedJavaRef

- introduces JavaRef<> base class to allow passing refs without knowledge of their scope
- makes the ScopedJavaLocalRef and ScopedJavaGlobalRef consistent, in name, in methods available, and in conversions allowed.
Also updates some other minor base API changes whilst I'm in those files.

BUG=
TEST=doesn't break build...
