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/templates/login.tmpl: increased font size further using <span> style. changed text to fit on two lines with the new size.

inputs/VegBIEN/TWiki/templates/login.tmpl: added large text with instructions to register (the TWiki instructions are small and easily missed)

added inputs/VegBIEN/TWiki/templates/login.tmpl
