Added in different Rho variables present in CMSSW706 miniAOD.  These Variables are

fixedGridRhoAll
fixedGridRhoFastjetAll
fixedGridRhoFastjetAllCalo
fixedGridRhoFastjetCentralCalo
fixedGridRhoFastjetCentralChargedPileUp
fixedGridRhoFastjetCentralNeutral

Kt6Rho was also removed

The new Rho variables have had setters, accessors, and storage variables added to TRootEvent.  Appropriate lines to populate these variables from the miniAOD were added into TopTreeProducer.cc

scripts/TOPTREE_fromminiAOD.py and scripts/crabConfig.py were both updated to contain all usefull collection names as well as references to CSA Relevant TTbar samples.
Merge branch 'CMSSW_70X' of https://github.com/TopBrussels/TopTreeProducer into CMSSW_70X
Forgot to add src/TopTreeProducer.cc in last commit.
