Update for fluid width text boxes

[steswinbank]

Added settings.distanceFromEdge so the cross will stay at the same distance from the right edge of the text box when window size is changed.

Thanks @steswinbank - this actually helps a lot in positioning the clear-href horizontally.

While your patch "hotfixes" my current problem, I really think removing the positioning code (or at least making it optional) would be the way to go – IMHO, the positioning of the clear-href should be done on the presentational layer, and I can't think of a reason not to do so (forgive me if I'm missing something here).

I'd also love a CSS-class on the wrapper-div (the one providing position:relative for the clear-href) as I'd like to give the input-element a padding-right equivalent to the width of the clear-href, but only when the clear-href is actually displayed … but that's another story (resulting from a usecase where the horizontal space for the input is very limited, and placeholder text is needed); if I find the time I might have a shot at this myself.

Thanks for the useful plugin and the patch!
