fix: inputs/.geoscrub/geoscrub_output/geoscrub.csv.run: make(): added warning that this will truncate the geoscrub database tables

inputs/.geoscrub/geoscrub_output/run: documented postprocess() rm=1 runtime (6 min)

fix: inputs/.geoscrub/geoscrub_output/postprocess.sql: map_geovalidity(): unscrubbable names should actually be geo*in*valid, not geovalid=NULL, according to Brad

fix: inputs/.geoscrub/geoscrub_output/: added _no_import because these tables are metadata that is used in the analytical DB. this is better than relying on bin/import_all not to import these.

inputs/input.Makefile: add: verify/: also svn:ignore *.log

*{.sh,run}: runscript targets: use begin_target instead of echo_func so the target name is properly echoed. note that this requires using with_rm so that $rm is properly progagated to applicable invoked targets. (previously, $rm was progagated to all invoked targets. note that with_rm only works inside a runscript target that starts with begin_target.)

inputs/.geoscrub/county_centroids/test.xml.ref, inputs/.NCBI/{names.src,nodes.src}/test.xml.ref: accepted test outputs (generated now that these tables are in import_order.txt)

inputs/input.Makefile: add!: verify/: also svn:ignore *.tsv, *.txt

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/.geoscrub/import_order.txt: added county_centroids so that it would be installed by new-style import
