fix: inputs/newWorld/: renamed to inputs/.newWorld/ (see issue #940)

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).

inputs/*/*/logs: updated svn:ignore

Added inputs/newWorld/newWorldCountries/ with postprocess.sql that sets isNewWorld to false wherever it's NULL. (The input table only marks New World countries as true, but doesn't mark non-New World countries as false.)
