Android: Add scoped local ref. handler.
Adds an internal class for handling local jni references. When calling
raw jni functions the returned object is usually a local reference, to
avoid overflowing the local reference table we need to free any local
ref. as soon as we're done with them. The class QJNIScopedLocalRef,
a QScopedPointer, makes this process a lot easier.
