clean up return values from local method
ask "continue anyway?" not "abort?"
fix unneeded ref/deref

Dist-Zilla-Plugin-PromptIfStale-0.002

          - fix documentation that referred to an option by the wrong name
          - inverted prompt, from "abort build?" to "continue anyway?" (with
            the default remaining as aborting the build/not continuing)
          - version checks are bypassed for modules provided by the dist being
            built
