Release v1.1.10

Fixes an issue where, if both _requireCourseCompleted and _requireAssessmentPassed are set to false, the course will still mark as completed/passed once you complete all blocks or pass/fail the assessment; and another issue where, if _requireAssessmentPassed is false and _requireCourseCompleted is true and the user completes all blocks and fails the assessment, the lesson_status will get set to completed then back to 'incomplete' (or 'failed', depending on the value assigned to _onAssessmentFailure) again
