Change motionFunctionsLib.py to inlude some functions to set/get EnableStopWithAnyLimitSwitch, and to set it to False in axisInit()

Describe the way to test your code:

1. Go to MainVisu, drive the axis to a limit switch, check if EnableStopWithAnyLimitSwitch is On, and make sure that you cannot run the motor because of this bit.
2. Run fat_sat_tools, python ctrlRunTests.py.
3. Just after asking if py-ads-monitor is on, one of the first thing it will do is to disable this bit.
4. Then fat_sat_tools should work normally.
5. if you copy all commands from the prompt, and paste onto notepad, and search for "disabl", you must find only one occurance, because there is an if statement to set this to False only once.
