Minor holy order fix

This is a vanilla issue.
Added Israelite cultural building
Added Nahuatl cultural building

Updated to PB building specs, just like the Israelite building
Vanilla Beta 2.1.5.3 Update

Not sure whether you'll want this change, but it's the only stuff that
doesn't require the new localisations.
Updated PB+SWMH culture buildings

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

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 = { }.
Merge pull request #163 from zijistark/alpha

Succession law title laws copy grantee upon new grant + 1 major one-liner
Minor decision update

This was a recent vanilla change that didn't get brought over.
Removed errant semicolon
Restored vanilla tournaments

We might as well have something functional until the New Duel Engine
version is fixed.
