added several b->JpsiKshh and b->Kshhgamma dec files
Several Kshh[Jpsi,gamma] dec files, with KS forced to decay before the TT. For the radiative cases, a gamma_PT > 1.8 GeV cut is applied. The Khh system comprises a cocktail of resonances so ==> was used in the decay descriptor. However this led to MCDecayTreeTuple getting confused between the multiple photons from the radiative b decay and PHOTOS. The decays printed out PrintMCTree seems fine.
