- point to main Calamares site in the 'part of' headers instead of to github (this is the "this file is part of Calamares" opening line for most files). - remove boilerplate from all source files, CMake modules and completions, this is the 3-paragraph summary of the GPL-3.0-or-later, which has a meaning entirely covered by the SPDX tag.
