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

inputs/*/*/test.xml.ref: updated source.shortname for new datasource name, which now starts out with .new suffix

bugfix: inputs/*/Source/data.csv for new-style datasources: need to include a blank row (plus a blank header) so that the metadata values are imported at least once instead of zero times, now that there is an installed staging table that will be iterated over. the blank row did not used to be necessary, because db_xml.put_table() has a special case for metadata-only tables with no installed table, which avoids iterating over the table's rows.

schemas/vegbien.sql: Renamed sampletype to observationtype to match the VegCore term

inputs/*/Source/map.csv for non-herbaria: Mapped sampleType

mappings/VegCore-VegBIEN.csv: source table mappings: Set shortname to env var $source when it's not explicitly specified, because shortname is a required field of source

db_xml.py: put(): _setDefault(): Support setting multiple col_defaults at once by using the param names themselves as the column names

mappings/VegCore-VegBIEN.csv: Set the source_id col_default to the datasource name using the new _setDefault() built-in function and _env()

Added inputs/FIA/Source/, containing referenceType metadata
