add version to provider_details and _history

Browse Source 
set all existing rows to have a version of 1 (also copy across values
to populate the new provider_details_history table in the upgrade
script)

in dao_update_provider_details bump the provider_details.version by 1
and then duplicate into the history table as a new row
(done manually as opposed to the decorator used in template_history
since this is only edited in this one place and the decorator is icky)
