Add bo record to set every ST channel all at once.

Before this, you would need to put array of values into ST-S.
Now you can simply put 1 or 0 into AllST-S and it will set all channels.

OOPT "on change" field is needed because for some reason without it even
if you put PINI=NO in all these three ST-S records, it processes on IOC
initialization, which I don't think is desired.
