Allow styling capability to <maplink> and <mapframe>. This is especially important for <maplink> because the link may be shown as a colored block, all of which should be clickable.

Example: <maplink style="font-weight:bold; padding: 0pt 0.1em 0pt 0.35em; border: 3px solid #000" .../> would expand into <a style='font-weight:bold; padding...'>...</a>
