validation/aggregating/*/*.sql, schemas/vegbien.sql, lib/runscripts/validations.pg.sql.run, inputs/bien2_traits/validations.sql: added _ to beginning of each view name so the validation views would sort at the top in the datasource's tables list. this will also make the validation result sets easily distinguishable from the data tables.

bugfix: lib/runscripts/validations.pg.sql.run: updated table match pattern to include the type prefix that validations queries now contain

bugfix: lib/runscripts/validations.pg.sql.run: --table: need to include explicit schema so that matching tables from other schemas are not included

added lib/runscripts/validations.pg.sql.run

lib/runscripts/file.pg.sql.run, schema.pg.sql.run: support custom options to pg_dump in $@

lib/runscripts/in_datasrc_dir.run: datasrc_make(): use `if remaking ...` instead of accessing $_remake manually, for clarity

bugfix: lib/runscripts/in_datasrc_dir.run: datasrc_make(): use set_make_vars and $_remake as required in lib/sh/make.sh `remaking`

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).

lib/runscripts/table.run: added test_() target and use it in remake_VegBIEN_mappings() (it would not be clear that remake_VegBIEN_mappings() runs the tests)

bugfix: lib/runscripts/datasrc_dir.run: import(): don't run `sql/install` if the schema already exists, because this will try to rerun all the schema-creation queries. note that this idempotent functionality was not provided by the `make .../install` target that was previously used (idempotency is new with new-style import).
