Add option for custom class on the anchor tag

[kemiley]

Custom class would allow for the use of different images/colors depending on context (ie, if user switches language). Also would be appreciated to have the inline styles removed and applied as a class or through the jQuery so that they could be overwritten with CSS.

+1 Would also help to have multiple instances on the page. I have a project that requires a "Back to Top" at the bottom right as well as a "Contact Us" at the top right.
