Only write updated Parameters.log on one MPI rank #18

This should fix #17. The Parameters.log file is only written by rank zero, which has the correct value for the TracerParticleTypes parameter.

I've also removed the first call to DumpParameters. I don't think there's any harm in just delaying writing the file out at all until we have the parameter values.
