schemas/VegBIEN/: moved Redmine/, TWiki/ to web/BIEN3/ since they relate to the BIEN3 project as a whole, not just the database
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 web/.twiki symlink to datasources/VegBIEN/TWiki/
