OnDoorToggle - Extra Plugin Functions Added

- OnDoorToggleAttempt(), called before CanOpenDoor
- OnDoorToggleFail(), called on CanOpenDoor = false
- OnDoorToggleSuccess(), called on CanOpenDoor = true or passively returned
- Corrected a minor comment mistake (ModifyServerTags)
- Forgot to check return value on OnDoorToggleFail, fixed
- Updated to pass initial result data onto OnDoorToggleFail (probably not needed, but best to cover all bases)
