Tweaked religious authority defines: A New Hope

Catholics are still pretty boned when the antipope arrives but a
few short years after start, but dangit, they ain't so boned as to
completely roll-over. I was also trying to work on the Sunni RA
problem in 1066 starts, which should now at least have improved.
I tried a few different approaches, but only 3 tweaks were required.
