Manually creating an RC file was the Qt 4 way. The Qt 5 way is just
giving it an icon.
When an RC_FILE isn't manually created Qt will attempt to create one. If
there are non-integers in the version number the compilation will crash.
AdvancedSettings_resource.rc is a build artifact on Windows.
The additional files packaged with the installer have been moved to
their own dir to separate them from the C++ source.
All licenses are now also included in the installer, as per the terms.
The version string in overlaycontroller.h has been updated to 2.8.0.
