inputs/CVS/^taxon_observation.**.sample/create.sql: added Mike Lee's additional plots used to validate confidentiality-related fields (wiki.vegpath.org/CVS_validation#plots-to-include)

bugfix: inputs/CVS/^taxon_observation.**.sample/create.sql: include taxonName in the subset of columns that's imported for the validation, because it is _alt-ed with scientificName for forming the TNRS input name. this is unique to CVS, which is why it was not part of the validation subset copied from the VegBank subset.

/README.TXT: Full database import: documented that you should always start with a clean shell, which does not have changes to the env vars. (there have been inexplicable bugs that went away after closing and reopening the terminal window.) note that running `exec bash` is not sufficient to reset the env vars.

fix: lib/sh/util.sh: verbosity_min(): usage: clarified that '' is a special value that causes $verbosity to be overwritten to ''

lib/runscripts/table.run: added test_() target and use it in remake_VegBIEN_mappings() (it would not be clear that remake_VegBIEN_mappings() runs the tests)

bugfix: inputs/.TNRS/schema.sql: granted bien_read SELECT access to derived views as well as the core tnrs table

updated inputs/datasource_release_status.xlsx

added inputs/datasource_release_status.xlsx, export of Google spreadsheet at https://docs.google.com/spreadsheet/ccc?key=0ArZXrTAXd-TYdDRRb2RxYi11TWZrQVh5bVdKOURCeFE

planning/timeline/timeline.2013.xls: updated for progress

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.
