fix: inputs/test_taxonomic_names/Taxon/map.csv: scientificName: remapped to scientificName instead of taxonName as this does include the author for some names

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

inputs/input.Makefile: %/.map.csv.last_cleanup: Run fix_line_endings after canon/translate to standardize Python's \r\n line endings back to \n. This prevents issues with mixed line endings because LibreOffice (and probably Excel) treat all cell-internal line endings as \n but row line endings as whatever the file had, while text editors like jEdit translate all line endings to whatever the autodetected line ending is. (This creates spurious line ending diffs when a map spreadsheet containing multiline cells is edited in a text editor.)

mappings/VegCore.csv: Renamed *Binomial to *TaxonName because this field can store more ranks than just the genus+specificEpithet binomial (that goes in speciesBinomial)

mappings: Renamed *scientificName to *binomial because DwC defines the scientificName as "The full scientific name, with authorship and date information if known", but many datasources do not include the author in their scientific name, and the fields scientificName is mapped to in VegBIEN assume it does not include the author

Added inputs/test_taxonomic_names/
