added jXERHO to trigger EDM and implemented sumET fix

fixing the sumET container to be filled with MissingET for the algorithms, NoiseCut_MET, jXERHO and JWOJ. NoiseCUT_MET:Filling when passing the noise and eta cuts and after the bool useNegTowers jXERHO: summing after the rho substraction -> sumET_sub += Et_sub; JWOJ:Filling the ET_values[0] which is defined as scalar_ET. in jwoj.h this is defined as scalar_Et+=seed_Et;
