run on MINIAOD

First "real" attempt to run on Phys14 MINIAOD. 
- Isolation is completely missing in "KLeptonSelector" due to absence of IsoDeposit in the eventcontent
- event filter is removed temporary due to absence of missing beamHalo event content; CSCHaloFilter fails
- No MVA identification in MINIAOD - switch to cut based ID
- bDiscriminator is known to be missing
