I've made the appropriate updates to the Mapnik osm2pgsql import code so
that it will only add the automatic 'P' symbol to a parking area if
there is no access= tag or if there is access=public. Any other
access=<something> tag will prevent a P being added. 

It will take a week or two before the effect of this change will appear
on the rendered maps.

In addition I've added the access= key to the list of columns exported
to the PostgreSQL database so we can add further map styles to
differentiate other objects with access=<something> on the map.
