Since python from crontab seemed intractable, I replaced autoMX.py with a soft link that points at autoMX.sh.

This is a simple BASH script that looks at the LSC FB stat (C1:DAQ-DC0_C1LSC_STATUS), and runs the restart mxstream script if its non-zero.

So far its run 5 times successfully. I guess this is good enough for now. Later on, someone ought to make it loop over other FE, but this ought to catch 99% of the FB issues.
