Simplify form layout.

Add:
    templates/index.html
        -Simplify form layout: reduce the number of independent adjacent `div`s,
        and position `label`s above their corresponding `input` elements.

    static/sass/index.sass
        -Remove now superfluous positioning rules for the previous layout.
