	* libplanner/mrp-task-manager.c:
	(remove_parent_predecessors_from_dependency_graph),
	(remove_parent_from_dependency_graph),
	(add_parent_predecessors_to_dependency_graph),
	(add_parent_to_dependency_graph),
	(task_manager_build_dependency_graph),
	(task_manager_do_forward_pass), (task_manager_do_backward_pass),
	(check_move_traverse_recursive), (check_move_traverse),
	(mrp_task_manager_check_move):
	Fixed bug #382548. Planner now correctly detects loops that would be created
	by indenting a task that is a predecessor of the task that would become its
	parent, so it will no longer crash trying to undo an invalid action.
	* tests/task-test.c: (main):
	Added regression tests for bug #382548 and related issues.
