    keyword=RICH crl change and logic change

    I added the trick that Bodo used in the previous experiment, the likelihood of all channels of an ADC firing being low for good events, we throw ADC channels which have more than 60 hits. I also added a condition on the track and hold which should solve the deadtime with other triggers. I guess I will like to take a run using this configuration to check the dead time improvement.

    I also added a veto on the fast clear of 500 uS triggered by the level one accept to prevent the event being cleared by another T3 during the readout.

    Still need to take a new pedestal run for the RICH too.
