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).

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

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/*/ which do not contain any explicit collisions (wiki.vegpath.org/2013-06-27_conference_call#To-do-for-Aaron > #3.2 > the following datasources ...): switched to new-style import, which adds the staging table column renaming

inputs/*/Source/VegBIEN.csv: regenerated for new-style import, which uses a symlink to mappings/VegCore-VegBIEN.csv instead of a custom mapping using the original column names

inputs/*/*/map.csv for CSV tables with a row_num column: added missing row_num entry, which is needed by the staging table column renaming to make the order of the map.csv columns match the order in the staging table

bugfix: inputs/*/Source/map.csv: added missing row_num entry, which is needed by the staging table column renaming to make the order of the map.csv columns match the order in the staging table. the staging table column renaming is now used by all Source tables.

bugfix: inputs/*/Source/: added missing ./run, which creates the new-style staging tables with the metadata fields as part of the table. this is needed now that these subdirs use installed staging tables instead of metadata-only map.csvs.
