bugfix: **/postprocess.sql: don't use the public schema, because this creates an unsatisfied dependency while the database is being installed, and breaks `make install`

inputs/VegBank/plot/postprocess.sql: remove institutions that we have direct data for: CVS: updated runtime (same)

bugfix: inputs/VegBank/plot/postprocess.sql: use CVS.plot_ instead because that has the renamed staging table columns, and is compatible with auto-renaming of the SQL script columns

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).

bugfix: inputs/VegBank/plot/: added _no_import because this table is left-joined and should not be imported separately

inputs/VegBank/plot/postprocess.sql: locality: include the site name (authorlocation), because this is part of the unique specification of the place that was sampled

bugfix: inputs/VegBank/: need to remove inter-datasource duplicates from plot instead of the left-joined plot_ table, because the fkeys needed to do the cascading deletes are all to the plot table. this requires doing the column-renaming and postprocessing on plot before it's left-joined.
