Re-add search view script (delete in d3332e7)

This script is required for geoserver to search for things properly.

In an ideal world you wouldn't need this script at all.
See issue OpenTreeMap#34 on github.

+--  Create a tree_search view
+--    This view is used by geoserver to run cql queries from the search page.
+--    Fields not included in the advanced filters may be removed. Check the views code 
+--    to make sure a field does not help resolve some other fileter before removing.
+--
+--    Stewardship date columns may need to be altered if the choices for stewardship
+--    fields are changed.

+--    Add this view as a layer to geoserver and use it as the GEOSERVER_GEO_LAYER setting
