[BLAST_SHIFTS] missing L0-L7

I do not make sense of this. The problems seems to "come" at a certain
time in the last two shifts and the trigger file seems ok.

However we have had "noise" problems in the ecl custom patch (ask Chris di
Andrea) with the NC bits, which seemed to be always firing. We thought we
fixed this. It also possible that after "checking" the timing you swapped
a cable polarity. I checked that last with VZ on thursday, there are ways
to get confused.
 
we should try putting the NC bits always in x mode (also for the front
tofs). In that way also a flipped cable (most always 1) would not affect
the trigger rate.
