2.05.3:nivve:6 New Shattered World submod

Alternate scenarios rebuild to implement more bookmarks and fix all the
present dukes and such. I also pre-actively disabled byzantium and papal
county allocation, adapted from my own mods. This makes the pope ruler
of b_roma instead of c_roma and byzantium will not be assigned
automatically in maintenence_events (this to prevent them constantly
popping up in the middle of counts).
Bookmarks:
- Shattered world 867
- Reign of Princes 867
- Shattered World 1066
- Reign of Princes 1066
