General overhaul of license and copyright information

The GPL license text is now located in GPLv3.txt. LICENSE.txt contains licenses
and copyright information for all bundled files from other sources and
AUTHORS.txt lists all contributors (taken from "git log").

At the same time, manual.txt was renamed to MANUAL.txt for consistency reasons.
