Sets the width of a file input element (also in Firefox!)
The jQuery.inputFileWidth plugin sets the width of an input file element.
Normally this can done with CSS, but the Firefox
browser don't support this. This plugin used a workaround to set the width
also in Firefox. It used the size attribute from the input element to change
the width. The calculated size is unfortunately only a approximation to the
real size, so there can be a deviation of some pixels to the desired size.
