validation/**: removed old versions of by=-tagged files. these were not renamed in the last commit because there were newer versions that they collided with. note that because , sorts before . , the newer version (with more ",name@inst" tags) was correctly renamed instead of the older version.

validation/**: removed by=... indicators so that we don't have to add an author name every time a file is changed. the author indicator is not needed now that both Brad's and my edits are open-source.
