web/BIEN3/TWiki/twiki.conf: updated paths
schemas/VegBIEN/: moved Redmine/, TWiki/ to web/BIEN3/ since they relate to the BIEN3 project as a whole, not just the database
merged inputs/VegBIEN into schemas/VegBIEN, since for the purposes of the data dictionary URLs, VegBIEN is primarily an exchange schema
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/VegBIEN/TWiki/twiki.conf: main TWiki dir: changed redirect to go directly to the Main TWiki web, so that we don't need to worry about creating different "webs" (subsites) for top-level wiki pages
inputs/VegBIEN/TWiki/twiki.conf: main TWiki dir: redirect shortened wiki page URLs of the form vegpath.org/twiki/Path to do/view/ for use with VegPath
added inputs/VegBIEN/TWiki/twiki.conf
