Update 7.0.X Branch

 * update to CMSSW_7_0_6_patch1 (miniAOD fixes)
 * forward-port to 7.0.6 the following  pull requests that were already merged in 5.3.X: #45, #47, #48, #54, #55, #56, #59, #60, #61, #62
 * put some very basic lepton ids (see issue #63)
 * update input files to a mix of a relval (to test running from DBS, but see issue #65), private copy of a centrally-produced miniAOD and privately-produced miniAODs.
 * for the TTH/Susy framework, the following CFGs run: susy core, susy multilepton, susy lepton study, tth (newNtpl one). the hadronic needs updates since it uses directly some CMG input collections which have to be migrated to miniAOD
