remove direct calls of DQMStore, move SusyPostProcessor to DQMHarvester

leftover calls of DQMStore and beginJob and endJob have been removed from all modules (endRun where not needed as well), the SusyPostProcessor has been move to DQMEDHarvester class.

The code was checked by running the matrix, since we call a value map for the ak4jetid of calojets, which has been added to the RECO sequence only recently. Development started from 7_1_X_2014-5-19-0200
