MarionL - refactoring Project/Story resources.

-Moved getStoriesByProject to StoryResource.
-Cleaned up path for story. It should pass-in projectid for
authorization purposes as part of the path.
-found another spot for calling UserUtil.
-removed the Consumes(JSON) from functions, it is stated at the top of
the class so it will be inherited in each function (hence its
redundant).
