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/*/Source/ for new-style datasources: use an actual staging table instead of a metadata-only table, so that metadata values can be stored in the staging table instead of the map.csv (as will be required by new-style import)
