Improved attendance project tracking capabilities are exposed through the V2 Projects and Project Members endpoints

newly introduced advanced Project attributes are returned when getting and listing Projects and can be set when creating and updating Projects.
a new concept of Subprojects exists which are modeled by setting a parent_project.id.
new endpoints also exist for managing employee assignment to projects (for projects that have not been assigned to any individual, the assigned_to_all attribute controls whether it is available to all employees to track or to none).
