*{.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.)

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).

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.

added inputs/FIA/_src/run, which runs ./download

inputs/FIA/_src/Makefile: Extraction: $(zips): use $(allZips) containing a zip for each state so that states that have not yet been downloaded and extracted (or had an empty dir created for them) will be downloaded. previously, the extract target only expanded existing zips but did not download new zips unless no zips had yet been downloaded. (this had been necessary because some states do not have a download, and the download of them would be continuously retried every time the Makefile was run.)

bugfix: inputs/FIA/_src/Makefile: `%: %.zip`: if unzip fails because the download does not exist, create an empty dir for the state instead of aborting make

inputs/FIA/_src/Makefile: use curl instead of wget because that is also available on Mac
