pelican-theme: Strip tags from <title> element

A reader of my blog reported a rendering bug
(https://mastodon.social/@sil/117146095868899305), which looks similar
to https://github.com/getpelican/pelican/issues/1930.  The Pelican
maintainers said that this was a theme issue, so I think the `m.css`
theme should be tweaked to handle this properly.
