*{.sh,run}: use new begin_target instead of `echo_func; set_make_vars`

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).

BIEN2/country_species/: svn:ignore the .tsv exports

BIEN2/country_species/run: documented runtime (1 min)

added BIEN2/country_species/run, which exports each BIEN2 country's species list
