fix: inputs/FIA/PLOT/map.csv: added plotArea_ha, requested by Brian McGill

fix: mappings/VegCore-VegBIEN.csv: mapped DwC year/month/day, which are split-date alternatives to eventDate. this fixes the missing eventDate in FIA.

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/FIA/*/map.csv: use -- to separate the table and column name instead of - , to conform with the u-name format (wiki.vegpath.org/u-name#format), which works even when only one of _- can be used in the name. -s are needed in this case to linewrap the column on a separate line as the table in phpPgAdmin.

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

bugfix: inputs/input.Makefile: %/VegBIEN.csv: for new-style datasources, use a symlink to mappings/VegCore-VegBIEN.csv directly instead of prefiltering VegCore-VegBIEN.csv to include only the columns in map.csv. prefiltering used to be performed as part of mapping the map.csv VegCore output terms to VegBIEN using bin/join, but is no longer needed because the staging table columns are now VegCore terms. instead, the full VegCore-VegBIEN.csv is needed so that derived columns added in stage I or II validations are detected by bin/map (rather than just the original source columns in map.csv).

added inputs/FIA/*/{VegBIEN.csv,test.xml.ref}, which are now generated by the mapping process for the joined-together tables (even though they are not used by the import, because only occurrence_all is imported)

inputs/FIA/*/postprocess.sql: removed svn:executable attribute using `svn pdel svn:executable ...` now that these are not shell scripts

inputs/FIA/*/import: changed to postprocess.sql for use by the runscripts
