Fix broken links
I went through the archives of this website and cleaned up URLs that no longer lead to anywhere useful.
- Bad links to third-party websites have either been updated to be alive again, to point to Web Archive, or plain removed.
- Links to my old website were removed. This means some of images have not been available for a long time. I still have them stored locally and may re-publish them eventually. Photo galleries are gone, as I won’t have space for them on the hosting.
