For all element names defined in SVG 1.1 (for now), make the parser
treat it just as it would have if it had parsed "<svg><g>...", except
that it obviously wouldn't output the <svg> element.

There are a few tags where this is a big problem. At least for <a>,
<script> and <style> appear both in SVG and HTML and so for markup
like "<a>...", "<style>..." and "<script>..." we don't know which
namespace to create the element in. Fortunately these elements behave
mostly the same no matter which namespace they are created in.

Unfortunately <style> and <script> are parsed differently depending on
if they live in foreign content or not. However this is something we
can fix, and would lead to a lot of other benefits (such as scripts
parsed consistently when moved around in the markup).
