Bug 527110 - Issue with serialization code in Generic Editor

Deprecate save/load methods of ResourceSetHelpers that do not expect
resource set saving/loading options. Clients are responsible for passing
in the expected options and the helper class should not specify any.

Removed warnings in changed code.
