[PATCH v2] Documentation: add logo to site header

[Valentin Gagarin <valentin@gagarin.work>]

Also spell out the title.  The stylesheet adjustment makes the logo
align properly with the longer title text for different display widths.
Override the [title template] to show both the title text and the logo.

[title template]: https://github.com/just-the-docs/just-the-docs/blob/f43d7cfc4b1e18a97e6d6d20b88f1aaeda0e7196/_includes/title.html
