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).

inputs/*/*/map.csv for CSV tables with a row_num column: added missing row_num entry, which is needed by the staging table column renaming to make the order of the map.csv columns match the order in the staging table

mappings/VegCore-VegBIEN.csv, inputs/*/*/map.csv: Applied term renamings from the new dynamically generated Veg+-VegCore.csv, which reflects the current state of the data dictionary. (Permanently switching to the new Veg+-VegCore.csv will be a separate change.) Updates to VegCore term names that have occurred since the data dictionary was created are now able to take effect, which involves remapping and inferring units on several fields.

mappings/VegCore.csv: Regenerated from wiki

mappings/VegCore.csv: Terms: Removed namespace prefixes (dcterms:), because VegCore terms are globally unique within VegCore and there should not be multiple versions of the same VegCore term with different namespaces. Provenance is instead indicated in the Sources column, which contains not just a namespace but a full URL to each source term.

Added inputs/NVS/Coordinates/
