XD-713 @Configuration modules!

Adds support for JavaConfiguredModule. ModuleFactoryTests loads an uberjar built as a separate project. The module project zip is also included for reference. 

2nd commit addresses XD-1085 (groovy modules) - added to this PR because I updated ModuleFactoryTests which is new in this branch.
Not sure I understand what that .zip file is about. Does it contain the *sources* to the eponym module?
