    keyword=PVDIS crate in HAPPEX

    First of all, to be conservative, I did not change the "Transversity"
    config in HAPPEX DAQ.

    Next, I created another config "TransPvdis" which has the PVDIS
    crate added. This will be very useful for PVDIS parasites and
    will be how we run that experiment next year. From the POV of
    Transversity there should be *no* observable difference - feedback
    still works, all scripts the same, datastream the same except that
    a new crate (ROC28) comes along for the ride.

    Details about how to switch, etc:

    (click on PVDIS DAQ).

    I will propose we run with TransPvdis for some (~50%) of
    production. The PVDIS crate can still run standalone without
    hardware modification.
