Allow for customizing output

[mkupper]

At present Send Tab URLs supports three layouts (plain, numbered, and bullets). I'd love to see a way to customize the layout so that it generates a one line per tab result such as:
    {tab}{url}{tab}{title}{newline}

The existing layouts that are available would be
    {title}{newline}{url}{newline}{newline}
    {number}. {title}{newline}{url}{newline}{newline}
    - {title}{newline}{url}{newline}{newline}
