Allow extra columns for Controls file

[mrrezaie]

Hi, if the Controls file in Analyze tool has extra columns, a pop-up error appears:

Control with name 'pelvis_tilt_actuator' provided in the ControlSet 'Control Set', but no matching Actuator was found in the model.
In Object 'controlsetcontroller' of type ControlSetController.
Thrown at ControlSetController.cpp:309 in extendConnectToModel().

Would it be possible to make it more flexible? For example, just print a warning that the actuator doesn't exist, so the controller ignored.

Thank you in advance.
