Required page auto-creation, shortcodes, settings, views for list/detail

Pages are no longer duplicated upon auto-creation if it finds a slug
corresponding to the given page name: it will instead replace the option.
Required pages given a different admin management display, can no longer
edit ID or slug, which are instead derived through the page name. (this
is not yet functional though!)
Views for List and Detail have been updated. List has a new view file
called 'grid' which can be selected in the options and through a shortcode.
Map and search filters can now be auto-opened on page load or not dependent
on an option or shortcode.
Database scripts updated to suit new options.
