bugfix: inputs/analytical_db/: need dummy table.run file to cause a schema to be created for this datasource

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).

added inputs/analytical_db/_archive/

inputs/analytical_db/: removed import-related files (Source/, etc.), since this is actually just a folder used to store make_analytical_db.log.sql, so that it will be synced along with the other logs

inputs/analytical_db/: added _no_import to prevent this from incorrectly being included in the source table

inputs/*/Source/VegBIEN.csv: regenerated for new-style import, which uses a symlink to mappings/VegCore-VegBIEN.csv instead of a custom mapping using the original column names

bugfix: inputs/*/Source/map.csv: 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. the staging table column renaming is now used by all Source tables.

added inputs/analytical_db/table.run

bugfix: inputs/*/Source/: added missing ./run, which creates the new-style staging tables with the metadata fields as part of the table. this is needed now that these subdirs use installed staging tables instead of metadata-only map.csvs.

inputs/*/: added top-level Makefile which includes inputs/input.Makefile, so that make can be run directly on the datasrc dir without needing to specify `--makefile=../input.Makefile` (see input.Makefile $(selfMake))
