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).

Refreshed SALVIAS

inputs/SALVIAS/: Regenerated salvias_*.schema.sql from the MySQL version, to take advantage of my2pg improvements. The placeholder *_index columns which take the place of MySQL's inline index definitions have now been replaced by no-op CHECK constraints, so that there are no longer lots of dummy *_index columns in the map spreadsheets.

inputs/SALVIAS/: Switched to using the DB export's staging tables instead of the exported CSVs
