Removed superfluous normalisation of spin directions (now done at input stage)
Bugfix: Changed random spin initialisation to be uniform on unit sphere and to be correct for parallel simulations, with unique directions on all CPUs
Bugfix: Fixed parallel periodic boundary conditions by allowing self transfers of halo atoms
Incremented version to 3.0.2
