Small website update

I've found a new pelican template that makes older content better accessible through a more compact tag and categories page. Also, this has stork for search integrated. Not sure how useful this will be, but let's find out.

Secondly I'm moving the blog to https://blog.lutra-it.eu/. This nicely fits in with me running my Fediverse presence at social.lutra-it-eu since last week. The old URL will work with redirects for some time to come. The new web address is still services from my VM at OpenBSD.Amsterdam ;)
