add support for querying descendants in the rest api (useful for graphs!)
misc cleanup to REST API - move /application/reloadBrooklynProperties to /server/properties/reload - better resource, and more consistent name (@nakomis can you review?); and remove deprecation, redundancy
code review - try to find the right sensor better
