/LICENSE.TXT: moved emphasized sections to top

/LICENSE.TXT: changed "the open-source parts of the repository" to "the repository's components" so that this sentence makes sense once the non-open-source exception is removed

/LICENSE.TXT: documented that the non-open-source files are now listed in _license/non-open-source/applies_to.txt

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

added _license/PostgreSQL_config (for schemas/*.conf)

*/LICENSE.TXT: GPL: removed divider between the copyright header and license text, since these are part of the same license

/LICENSE.TXT: added note that when redistributing, it recommended to include _license/, so that the open-source proof is included along with the license text (this information should be here as well as in _license/README.TXT because redistributors might not think to look in that file)

/LICENSE.TXT: removed "svn" before "repository" because this would apply equally to a git export of the repository

/LICENSE.TXT: replaced "portions" with "parts" for consistency with the _license/README.TXT wording

/LICENSE.TXT: added collective license conditions (GPL2+) for the svn repository as a whole, except the non-open-source portions

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.
