This PR updates several doc blocks in the libraries/cms directory to better document containers and return types. For containers that store a specific object type, the doc block is updated from a generic array to the doc block representation that an array of an object type is stored (i.e. JApplicationCms[]). For doc blocks that indicated @return object, doc blocks are updated to provide a more specific return type (either the actual object or stdClass in the case that object type is actually returned).
