Update to RHadron Mass Spectrum for Spin Issue
We identified an issue in the treatment of spins in the R-mesons, which requires one more fix to the masses. Along the way, we also fixed a rounding issue in the calculation's output which leads to a few other 1 MeV differences here and there, and fixed a couple of just outright bugs from typos. These changes are also in svn, and should go ~everywhere in git.
