OBS: Setup Weekly Builds and use autochangelog macro #2812
Description
Is your feature request related to a problem? Please describe.
Open Build Service is a new integration. Want to start offering weekly builds for testers and others who want super current code.
Describe the solution you'd like
As the new code in .obs becomes a bit more stable and we move away from the sandbox to the real longturn project, setup weekly releases.
Along with this, see about the usage of the %autochangelog macro in the .obs/freeciv21.spec file.
