Nothing big changed, except for the included private headers/cpp files for building on systems with no internet connection.

Bump version for homebrew.

Initial working version.

Do not download sources during a Gentoo package build.

Rather than trying to access the network, error out when the private
Qt5 files are not found among the cached versions.
