moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).

schemas/vegbien.sql: plot.**, analytical_stem_view, analytical_plot: added project_contributors

schemas/vegbien.sql: added project_contributors()

schemas/vegbien.sql: analytical_stem_view: scientificName_verbatim: don't use taxonverbatim.taxonname+author as the scientificName_verbatim if only the author is provided. (this lead to weird scientificName_verbatims that contain just the author.)

bugfix: schemas/vegbien.sql: location: use the place_id from the parent location when no place_id is specified. this fixes a bug in analytical_stem_view where the parent location's place_id was used because it was sometimes missing from the sublocation, but the parent place_id itself was sometimes missing instead if sublocations each had their own place information. this way, it is always available directly in the sublocation, populated from the parent location if needed.

bugfix: schemas/vegbien.sql: location: added place_id which is autopopulated from the current locationplace. join on this in plot.**, to avoid a 1:many join when a location has multiple locationplaces.

bugfix: schemas/vegbien.sql: locationevent_unique_within_parent_by_location unique index: need COALESCE around location_id since it's nullable

fix: schemas/vegbien.sql: analytical_specimen: added specimens-related columns that are in analytical_plot

bugfix: schemas/vegbien.sql: updated for renamed county_centroids column names

schemas/vegbien.sql: include the family_higher_plant_group lookup table values so that these don't need to be regenerated from the NCBI nodes whenever the DB is reloaded
