Updating generic documentation files (AUTHORS, COPYING, README, etc.)

I was looking into updating the README files with respect to non- historical branding references to KDE/KDE3. So as to not incorrectly update historical references, updating those files probably is a file-by-file project. There are 966 README files and that basically stopped my motivation for updating the files. Further, there are 287 AUTHORS files, 275 ChangeL|log, 298 COPYING*, 173 INSTALL, 116 NEWS, 7 PACKAGING, 11 RELEASE*, and 366 TODO. I suspect many --- possibly most --- of these text files provide little to no value anymore. The AUTHORS files are redundant of the Trinity About dialogs, likely all of the change log files have not been updated since several releases before 3.5.10 and certainly have not been updated in the Trinity era, the COPYING* files are redundant to almost all *.cpp files, the INSTALL files are irrelevant at best, the NEWS files all are outdated, PACKAGING files obsolete, RELEASE files obsolete. There might be a handful of useful ideas in some of the TODO files, but likely they could be consolidated into a wiki page or bugzilla enhancement requests --- not that we have the available personnel to accomodate most of those wish list items. Should we delete most of these text files? Comments? Darrell
