Import all PB major_revolt CBs
All major_revolt CBs adjust dynlevy law immediately upon realm split
Merge pull request #101 from thefinestsieve/beta

Updated generic Muslim flavor text
dynlevy: sync laws on yearly pulse, for misc. realm_size changes

This could be made notably more efficient by creating a separate,
maintenance-only event that looks like emf_dynlevy.20 but includes
a trigger for higher_tier_than = count. The generic event can't
filter those cases.
Changelog update
Merge pull request #102 from zijistark/dynlevy

dynlevy triggers for faction revolts and yearly pulse
MAX_JOINED_FACTIONS raised to 3, to account for AF taking a slot
Updated EMF holy order donation piety

It now matches the piety received in PB. (I agree that it should
probably be 100 rather than 75, but I'll update if we later change it in
PB.)
