(issue1801) Unify reference gauge finding code
The basic way as described in the method comment of the
determineRefGauge method is now used in the WINFOArtifact,
MainValuesService and RiverUtils.getGauge method.
RiverUtils.getGauge previously just returned the first
gauge found. While this is now a behavior change I believe
that it is always more correct then the undeterministic
behavior of the previous implmenentation.
