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).
Added inputs/SALVIAS/_src/salvias_data_access_controls.txt
inputs/SALVIAS/_src/: Added salvias_plots.sql.url to provide a link to where salvias_plots.sql was exported from (it was not a raw file given to us by the data provider)
inputs/SALVIAS/: Added _src/ subdir to store original DB export (before re-export in a PostgreSQL-compatible form)
