Implemented copying of relations on version command (if relation type demands it)
added reportsDir property
Added: missing changes for copy-relations-on-version
Added: InfoService, which holds configuration objects and repository info.

Background: currently, the thread-local name of the current repository (database) is schlepped around in many places.
This is a first step of cleaning up the API and replacing foo(osd, repositoryName) with foo(osd){ repositoryName=infoService.repositoryName ...)
Changed logging.
