bugfix: inputs/SALVIAS/plotMetadata_/map.csv: things mapped to project_participant: remapped to event__participant because these actually relate to the event, not the project, even though they seem like project-related fields

fix: inputs/SALVIAS/plotMetadata_/map.csv, inputs/Madidi/LocationObservation/map.csv: things mapped to communityID: remapped to communityName, which is what's used in analytical_stem (communityID is for numeric IDs)

inputs/SALVIAS/plotMetadata_/create.sql, map.csv: expanded plot_administrator:party_code_party_ and mapped plot_administrator_name to a 2nd project_participant

mappings/VegCore-VegBIEN.csv: project_participant: use [!...] negative lookahead assertion so that multiple project_participant columns will properly map to separate projectcontributor rows

inputs/SALVIAS/plotMetadata_/map.csv: mapped PrimOwnerID_name->project_participant

inputs/SALVIAS/plotMetadata_/create.sql: added join to PrimOwnerID:party_code_party_

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
