Adding checks in the API to assure the correct person is completeing a task based on the task's lane.
Adding lane to the Navigation item.
Adding a check to assure that unique user ids can be identified using task.data
Added some additional ldap entries to make testing and development easier.
Removed a big chunk of duplicate code from task_tests_api
Modified some of the helper functions to make it easier to test as specific users.
Added some additional bpmn models to the tests for testing lanes and roles.
* The Task.title returned to the front end will now attempt to process the "display_name" property for dot-notation syntax, making it possible to use this for multi-instance tasks,
but will work in all cases where we want he title to change based on values in the data model.
* Fixing a bug the test_study_api where it wasn't updated when we made recent changes to the different states of a study.
