    theme: add toc partial to single.html layout
    
    Single pages will now have a TOC auto-generated if they are above
    400 words in length.
    
    This can be controlled through the frontmatter of the post by
    setting `toc: false` if you don't want one.
    
    Right now it it default to show a TOC if there is no frontmatter.
