Update TrigCounter for Bliss 1.1.0
I updated for Mauro Rovezzi (BM16) the TrigCounter
for bliss 1.1.0. It's working fine according to him.
I guess you would like to merge this. Who wants to review the changes?
ping @berruyer @holger.witsch @pguillou
Note: class TrigCounter has been renamed TrigCounterController
-> change should be reflected in config interf.yml
