MaterialManager: use elements from NistManager
This changes the creation of elements from a custom definition to using Geant4 provided ones. Note: G4Element != simple material (e.g. G4_Al). While doing so, I also discovered a "bug" where we gave Vanadium the element symbol Ti (the physical element was still Vanadium though).
