Augments a DOM element with some helpful methods / getters.

Getters:
    - innerHTML
    - rawtext - returns text immediately inside the selected element
    - rawfulltext - same as rawtext, but also includes text inside nested elems
    - text - rawtext but trimmed, BR's replaced with \n, and entities decoded
    - fulltext

Note: <br> and <br /> are replaced with \n when using text and fulltext
