mappings/VegCore-VegBIEN.csv: mapped subspecies to new taxonverbatim.subspecies for easier access by validations queries

fix: inputs/CTFS/AggregateObservation/map.csv: field mapped to occurrenceID: remapped to aggregateOrganismObservationID because these are not specimen occurrences

inputs/input.Makefile: add!: verify/: also svn:ignore *.tsv, *.txt

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/{.NCBI,CTFS}/*.src/: added _no_import because these tables are left-joined and should not be imported separately

inputs/CTFS/*.src/: added test.xml.ref

inputs/CTFS/*.src/: added VegBIEN.csv

bugfix: inputs/CTFS/TaxonOccurrence*/map.csv: things mapped to taxonObservationID: remapped to taxonOccurrenceID since taxonObservationID is not mapped to anything in VegBIEN (denormalized VegCore doesn't distinguish between taxon occurrences and taxon observations of them)

bugfix: inputs/CTFS/import_order.txt: added *.src so that these would be installed under new-style import as well. this means that their columns will now be automapped, requiring the names to be renamed to VegCore names in */create.sql. note that VegCore taxonOccurrenceID has been renamed to taxonObservationID since this was last run.

**/new_terms.csv, unmapped_terms.csv updated (using `make missing_mappings`)
