bugfix: schemas/public_.sql: analytical_stem_view_modify(): updated to new analytical_stem_view column names

schemas/public_.sql: analytical_stem_view: applied data dictionary renamings, using the steps at wiki.vegpath.org/VegBIEN_schema_refactoring#apply-data-dictionary-renamings-to-database

schemas/public_.sql: added 2014-6-4.Iara_Lacher.reserve_prioritization

schemas/util.sql: lat_long_in_new_world(): use function rather than operator+search_path to allow inlining, which enables util.new_world() to only be evaluated once

bugfix: schemas/util.sql: operator @(postgis.geography, postgis.geography): must use wrapper function because st_coveredby() needs postgis to be in the search_path

fix: schemas/util.sql: point(): hide benign "Coordinate values were coerced into range [-180 -90, 180 90] for GEOGRAPHY" notices

schemas/public_.sql: 2014-6-12.Jeff_Ott.climatic_range_determinants: also include New World occurrences by coordinates, using new lat_long_in_new_world(). this modification (as requested by Jeff) will help reduce the false negatives filtered out by including only data with placenames.

schemas/public_.sql: added lat_long_in_new_world() wrapper around util.lat_long_in_new_world()

schemas/util.sql: lat_long_in_new_world(): documented that this includes false positives above and below the New World bounding box, as described in util.bounding_box()

schemas/util.sql: bounding_box(): documented that the geography type stores all edges as arcs of great circles, resulting in the latitude lines bulging outward from the true bounding box. this will create false positives above and below the bounding box.
