PAC Settings

First try on adding a seperate PAC settings table.

Patch Set 4: Fix Bootloop
Patch Set 6: always try create to create the PAC table to
             avoid changing the versioning and future merge issues
Patch Set 7: Revert back to create the table in the latest version
             handling code. This means when coming from an earlier
             version it is handled correctly. Everyone else needs
             to wipe.
