schemas/vegbien.sql: specimenreplicate.institution_id: renamed to duplicate_institutions_sourcelist_id, as decided in the conference calls (wiki.vegpath.org/2014-03-13_conference_call#schema-changes-2)

mappings/VegCore.htm: regenerated from wiki: rename specimenHolderInstitutions to specimen_duplicate_institutions, as decided in the 2014-03-13 conference call (wiki.vegpath.org/2014-03-13_conference_call#schema-changes-2). note that most schema changes (such as this one) involve mappings changes, which are handled automatically by `inputs/run postprocess; yes|make inputs/{NVS,SALVIAS,TEAM}/test`.

inputs/WIN/Specimen/test.xml.ref: updated to map.csv, which has eventDate->dateCollected

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/WIN/Specimen/unmapped_terms.csv: updated

mappings/VegCore-VegBIEN.csv: mapped municipality

bugfix: inputs/*/*/map.csv for specimen tables: remapped eventDate,day,month,year to *Collected, because a general date always applies to the observation itself rather than to any parent event (specimens don't have a parent event)
