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

inputs/bien_web/: switched to new-style import, using the steps at wiki.vegpath.org/Adding_new-style_import_to_a_datasource

inputs/bien_web/observation/VegBIEN.csv: regenerated now that *_index dummy columns have been removed

inputs/bien_web/bien_web.schema.sql: regenerated using bin/my2pg, to remove the *_index dummy columns so they don't create lots of OMIT#... staging table columns

inputs/*/*/map.csv: added distinguishing #... suffix (e.g. UNUSED#institutionID) to the special terms OMIT, PRIVATE, UNUSED (VegCore.vegpath.org#Special-terms) to avoid creating a collision in the staging table renaming

mappings/VegCore-VegBIEN.csv: cultivated, oldGrowth: use just cultivated if it's provided, rather than /_alt-ing it back with oldGrowth (which it was generated from)

bugfix: mappings/VegCore-VegBIEN.csv: fixed priority of cultivated and oldGrowth so cultivated is used first if it's available
