fix: inputs/.IRMNG/*/: added _no_import because this datasource is only used as a lookup table and does not need to be imported/scrubbed

bugfix: inputs/IRMNG/: renamed to inputs/.IRMNG/ so that this comes before TNRS, which depends on it (this is a metadata datasource, so it can start with "."). part of issue #940.

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).

fix: bin/map: put template: comment out the "Put template:" label so that the output is valid XML, and displays properly in a browser rather than showing a syntax error

bugfix: mappings/VegCore-VegBIEN.csv: nest all taxonoccurrences inside a stratum event, so that the parent locationevent is always fully populated before child locationevents point to it. (previously, a stub parent event was created when the child event was imported first, which blocked the fully-populated parent event from being inserted later on.) this uses auto-folding (for VegBank/CVS) and auto-forwarding (for other datasources) to prune empty stratum events for taxonoccurrences that don't have strata. (see wiki.vegpath.org/Auto-folding, wiki.vegpath.org/Auto-forwarding for more info about these normalization techniques.) note that the inserted row counts stay exactly the same for all datasources except VegBank (which was being fixed), indicating that this signficant change to the mappings did not change the semantics of the import of taxonoccurrences.

inputs/*/*/test.xml.ref: updated source.shortname for new datasource name, which now starts out with .new suffix

bugfix: inputs/input.Makefile: %/VegBIEN.csv: for new-style datasources, use a symlink to mappings/VegCore-VegBIEN.csv directly instead of prefiltering VegCore-VegBIEN.csv to include only the columns in map.csv. prefiltering used to be performed as part of mapping the map.csv VegCore output terms to VegBIEN using bin/join, but is no longer needed because the staging table columns are now VegCore terms. instead, the full VegCore-VegBIEN.csv is needed so that derived columns added in stage I or II validations are detected by bin/map (rather than just the original source columns in map.csv).

added inputs/IRMNG/species_homonyms/new_terms.csv

bugfix: inputs/IRMNG/*/map.csv: remapped Authority to scientificNameAuthorship instead of authors (now data_authors <VegCore.vegpath.org?data_authors> for clarity)

bugfix: inputs/IRMNG/species_homonyms/header.csv, map.csv: reset input columns to DSV (delim-separated values) header. they had gotten changed to the output names in running map.csv with remake=1, causing it to be remade from the (renamed) staging tables.

added inputs/IRMNG/, including runscripts to download the names. this is now the 2nd datasource after GBIF to use runscripts, and the 3rd after FIA/GBIF to use new-style import.
