added _license/GPL2.txt.url

_license/*/LICENSE.TXT: documented that the first section of the file is from license.eml.txt in each folder

/LICENSE.TXT, _license/VegBank_schema/LICENSE.TXT: moved text of the GPL2 license into separate file _license/GPL2.txt to avoid cluttering up LICENSE.TXT

added _license/VegBank_schema/applies_to.txt

added _license/TWiki/ (for inputs/VegBIEN/TWiki/)

_license/ESA/: renamed to VegBank_schema/ because this license applies only to the VegBank schema

_license/README.TXT: merged ¶2 into ¶1

_license/README.TXT: replaced "authority information proving the open-source status" with the simpler "open-source proof". clarified that each LICENSE.TXT is meant as a proof.

_license/README.TXT: clarified that this folder contains authority information proving the open-source status of parts of the codebase. added recommendation to include this folder when redistributing, so that the open-source proof is included along with the license text.

_license/LICENSE.TXT: renamed to README.TXT because this actually contains a description of the folder, not license text

_license/VegBank/: renamed to ESA/ following the convention that each _license/ subfolder is a copyright owner

added _license/VegBank/

added LICENSE.TXT and related files (in _license/). the open-source portions of the svn repository are licensed as described in _license/. note that some portions of the svn repository are NOT open-source. these are copyright their respective owners.
