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/: use installed staging table (with blank-line data.csv) in order to also work with new-style import. this also fixes a benign diff between the by-row and by-col test outputs, where row-based import would not import the Source/ entries because there was not at least one row in the input. note that in order to ensure that all datasources are properly run, you need to check `svn st|sort` against the datasource schema names to see if any are missing.

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/CVS/Source/, containing referenceType metadata
