Thin-to-thick arrow fix for BandQ decfiles

! 2018-12-12 - Simone Stracka Modified 13 decay files + 11134264 : Bd_chic1Kpi,pp=TightCut.dec + 11134003 : Bd_etacKpi,pp=DecProdCut,TightCut.dec + 11134004 : Bd_etacKpi=sqDalitz,pp=DecProdCut,TightCut.dec + 11134263 : Bd_hcKpi,pp=TightCut.dec + 11104070 : Bd_ppKpi=DecProdCut,TightCut.dec + 11144091 : Bd_psi2Spipi,mm=phsp,DecProdCut,TightCut.dec + 13144054 : Bs_psi2Spipi,mm=phsp,DecProdCut,TightCut.dec + 12143221 : Bu_X3823K,chic1g,Jpsig,mm=TightCuts.dec + 12245033 : Bu_X3872K,psig,mm=TightCuts.dec + 12133264 : Bu_chic1K,pp=TightCut.dec + 12243204 : Bu_chicK,Jpsig,mm=TightCuts.dec + 12133263 : Bu_hcK,pp=TightCut.dec + 12143211 : Bu_psi2SK,chic1g,Jpsig,mm=TightCuts.dec In the old decay file, the arrows are misused in LoKi descriptors. We have now changed '->' arrows to '=>' and modified the associated event types. The following ones have been replaced by the ones listed above: 11134262, 11134001, 11134002, 11134261, 11104072, 11144090, 13144053, 12143220, 12245032, 12133262, 12243202, 12133261, 12143210
