insert-annotations-to-source should take Target meta-annotation into account

[dbrosoft]

insert-annotations-to-source should issue a warning and decline to insert an annotation if the requested insertion location is not in the set indicated in the @Target meta-annotation on the annotation's definition, or in the default set if there is no explicit @Target. In particular, if the annotation's definition is annotated with @Target({}), it should not be inserted anywhere in the source.
