Sphinx-pythia-theme

This feature adds better ability to define a footer menu (with CSS classes), and it allows users to add custom Jinja templates for footer elements in their source directory (in the `_templates` subfolder).

This is a significant redesign of the theme to allow more features of the parent themes through (the Sphinx Book Theme, which inherits from the PyData Sphinx Theme). In addition to letting PyData and Book theme feature through, this release also adds a footer menu element to the bottom of the page. This element can be reordered with other elements in the footer.

This is bugfix release for certain incorrect stylings found on the Pythia Portal and Foundations book.

This is an update to the theme stylings. No significant new features.

Bugfix release!

This release implements a new feature allowing users to specify Sphinx `document` names as URL links in the *Domain Navigation* bar at the top of the Sphinx Pythia Theme pages (instead of valid URL links with the appropriate file extensions).
