added exports/2014-3-11.Jeff_Ott.climatic_range_determinants.csv.run

bugfix: exports/.rsync_filter.upload: *.csv: need to use `protect` rather than `hide` to prevent overwriting

fix: exports/.rsync_filter.upload: *.csv: don't allow test runs' exports to overwrite the backed up ones

*{.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).
