No scale

Hello,

Here is a set of tweaks that are not related to each other, but unfortunately all in one branch:
- list of prefixes that the organizer will not scale (useful, e.g. for efficiency curves made from MC)
- display /fb rather than /pb in histogram titles and plotter yield tables
- configurable optstat and fit func for plotter
- do not shift under/overflows for TProfiles
- CERN batch for CMS
