inputs/VegBank/plantconcept_/header.csv: Updated for new renames in vegbank.~.clean_up.sql

inputs/VegBank/plantconcept_/create.sql: Use new plantconcept_plantnames()

inputs/VegBank/vegbank.~.utils.sql: plantconcept_plantnames(): Use SQL SELECT query and WITH clause (http://www.postgresql.org/docs/8.4/static/queries-with.html) instead of temp table, because PostgreSQL does not support using temp tables inside functions that are called repeatedly (http://archives.postgresql.org/pgsql-general/2006-02/msg00516.php; it results in an "out of shared memory" error)

inputs/VegBank/vegbank.~.utils.sql: Removed hardcoded schema name, which is set dynamically by input.Makefile using `SET search_path`

inputs/VegBank/vegbank.~.utils.sql: Added plantconcept_plantnames()

inputs/VegBank/vegbank.~.utils.sql: plantconcept_ancestors(): Made function STABLE instead of IMMUTABLE because it accesses DB tables

inputs/VegBank/vegbank.~.clean_up.sql: Fixed bug where the original plantconcept table's columns needed to be renamed, rather than the derived table plantconcept_'s. Note that this script runs before any derived tables are created, so this would be the wrong place for these statements if the derived table's columns did need to be renamed.

input.Makefile: Staging tables installation: $(dbExports): Sort each group of .sql files in lexical order, since $(wildcard) apparently does not sort them that way automatically on vegbiendev

inputs/import.stats.xls: Updated with stats from latest import. Corrected input row count of CTFS.TaxonOccurrence, which had been set to the inserted row count (which is right above it in the log file).

schemas/vegbien.sql: taxonrank: Added comment documenting source of values
