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

mappings/VegCore-VegBIEN.csv: mapped subspecies to new taxonverbatim.subspecies for easier access by validations queries

*{.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/FIA/taxon_observation.**/header.csv: updated for new REF_RESEARCH_STATION.country metadata value col

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/FIA/TREE/run: documented import() runtime (1.5 h), which includes table cleanup runtime (1 h)

inputs/FIA/COND/postprocess.sql: filtering formula: documented that this was created by Brad, and provided the URL to it on nimoy

**/new_terms.csv, unmapped_terms.csv updated (using `make missing_mappings`)

copyright scrub: inputs/: removed data provider-owned schema and documentation files, which are not BIEN copyright and should not be part of what is submitted for open-sourcing. these files will remain accessible via the web interface (fs.vegpath.org), but will not be in the repository.
