REVIEW-3088: some tweaks on GradleBuild model request handling
- rename ConsumerConnectionBackedModelProducer to ModelBuilderBackedModelProducer
- fix if comparisions (eg. accidently used == instead of equals)
some changes on tooling-api related to REVIEW-3088
- implement moduleproducer for other ConsumerConnection implementation
- build GradleBuild from GradleProject instead of EclipseProject to avoid dragging in all kind of unrelated stuff.
