Currently currentBuild.result returns a string. This makes testing whether a result is better/worse than some status. This functionality is present in hudson.model.Result as isBetterOrEqualTo and isWorseOrEqualTo

Suggest one of two solutions:
1. Wiring this through as currentBuild.resultIsBetterOrEqualTo(String) and currentBuild.resultIsWorseOrEqualTo(String).
2. Add a currentBuild.resultValue property that returns the raw hudson.model.Result value from which someone could run isBetterOrEqualTo
