* Break circular dependency between core and util Created a new :common project and moved a minimum number of classes to break the circular dependency between the two projects. This gets rid of the gradle lint dependency warnings. Also separated api classes and testing helpers into separate source sets in :common so that testing classes may be restricted to test configurations.
