Title: CombineHarvester updates

* fix a few things that the last update broke in CMSSW 5_3_X
* Improvement to the handing of TH1s - resolves #502
- Observation, Process and Systematic classes are now responsible for
ensuring any TH1 passed in does not have negative bins, as well as
performing the scaling to unit integral
- The set_shape methods now take an extra bool which determines in the
norm value should be updated to the histogram integral or not
- New methods for getting clones or copies of the internal TH1 are
added
- basic implementation of flags to control the behaviour of
CombineHarvester added. Currently plan to hard-code these to
something sensible and add an interface later
- Rewrite VariableRebin to account for these changes
- Add small script for validating SM legacy cards
