Add a customizer setting to force the sidebar to the left (vs the "classic" responsive layout)
Use correct class/ID on site title preview, so the hide & color setting JS works
Wrap entire image circle in link, so that link still exists when the header text is hidden. Fixes #34
Accessibility: add a clear focus state.
Display header text in admin as it is on the frontend, use table-cell method for alignment rather than line-height as height, which only allows for one line of title text.
Correct the CSS on site title and description when customizing, pulled from _s.
Update the selector in the customizer js, as the a wraps the title now, `.site-title a` doesn't exist
Switch to using `.font-size` mixin rather than defining font size twice everywhere
