Not sure whether you'll want this change, but it's the only stuff that

They now have all the recent changes made to PB's cultural buildings,
including my Jewish and Nahuatl additions.

Merge pull request #162 from thefinestsieve/beta

Mostly building updates
Fix for succ_gavelkind potential; removed condition barring baronies
Fix for failure to copy grantee succ_law_title succ. laws upon grant

Behavior now properly mirrors that of vanilla, yet manages to maintain
PB's special allow = { } conditions, unused by vanilla and other major
mods for succession laws for a reason. Thank is_recent_grant and the
fact that 'recent' is shorter than the manual succession law change
minimum time since grant/usurp/inherit (in defines.lua).  Still a
poor substitute for a proper pass_allow = { } to correspond with
pass_effect = { }.
