New template

After many years, I decided to add a new template to the blog, for as long as I'm still using it, this being the Minima Black template, that I thought might fit the purpose even better than the last one. There are still, to be sure, some parts I'll want to smooth out. But for now, I think I've got most of the important parts in place, and so, I'll see how well I can manage with the new one now, and hope it'll be comprehensive enough for everybody, and easy to navigate.
