Textile reader: don't allow block HTML tags in inline contexts.

The reader previously did allow this, following redcloth,
which happily parses

    Html blocks can be <div>inlined</div> as well.

as

    <p>Html blocks can be <div>inlined</div> as well.</p>

This is invalid HTML, and this kind of thing can lead
to parsing problems (stack overflows) as well.  So this
commit undoes this behavior.  The above sample now produces;

    <p>Html blocks can be</p>
    <div>
    <p>inlined</p>
    </div>
    <p>as well.</p>
