added inputs/XAL/Specimen/data.csv (empty template)

mappings/VegCore-VegBIEN.csv: mapped subspecies to new taxonverbatim.subspecies for easier access by validations queries

inputs/XAL/Specimen/header.csv: updated

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/XAL/Specimen/test.xml.ref: updated for sample data.csv, which contains the columns as a CSV. this fixes a bug where a map.csv must be used on a table that contains the same set of columns (ie. not one with no columns if there are any mappings).

added inputs/XAL/Specimen/_no_import, since this is a demo-only datasource and there isn't a staging table for it

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).

bugfix: inputs/XAL/Specimen/, NY/Ecatalog_all/: *JulianDay: remapped to dayOfYear instead of day (the day of the month)

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
