Fix-span/doc

This meta-template is just like {{fix}} with three exceptions:

• It takes a content parameter containing wikitext to be placed within a <span/> element before the superscripted notice.
• It takes a span-class parameter specifying the HTML class name for the <span/> element.
• It gives special priority over text rather than the other way around.

The spanned content is displayed like this.

This is a separate template for now because this is an idea imported from the Italian Wikipedia (q.v.). Eventually, if this idea takes off, this mechanism could be folded into {{fix}}.
