Route spec consolidation and logging

Route consolidation via the config file using the 'additional_paths' key within a route spec .. which should be a JSON array of additional path strings to match for given spec. Before you had to duplicate the info for every route spec if you wanted multiple paths to be routed to a particular target.

MOJO_DEBUG_LEVEL=info now in Dockerfile to show the proxying lifecycle messages (delete if you don't want).
