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/REMIB/Specimen/header.csv: Regenerated for new staging tables format

inputs/*/*/header.csv: Regenerated for new staging tables format (which now includes a row_num column on every CSV table), as part of reinstalling staging tables

input.Makefile: Staging tables installation: `%/install: %/create.sql`: Don't add a row number column to the created table because it is now added automatically to the temp table by column-based import (row-based import now also does not require a pkey for DB inputs)

inputs/REMIB/Specimen/: Filter out invalid, frameshifted rows so they don't produce errors in the import or anomalies like thousands of taxondeterminations for one taxonoccurrence. This involves moving the CSVs to Specimen.src and using a create.sql to create the filtered table.
