    Add frontmatter option to ignore sub pages
    
    On section pages, which act like list pages, Jehan didn't want
    to see a listing of sub-pages on the branch (he wanted to do it
    manually).
    
    This commit sets a frontmatter option to suppress the list
    generation in the section template by setting frontmatter:
    
    ```
    show_sub: {true|false}
    ```
