Random patch storage

These are not meant for commit, but more as a proof of analysis, and starting point for proper fix:

#16, red cat.

Ugly, but roughly correct.

#48, red linktest failed

It's a bug inside KonqHistoryManager --- it ignores some inserts, which makes the link not :visited.

#71 testcase

With above, we fail at least the following in #71:

<script>
var doc = document;
doc.open();
doc.write("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\"><title><\/title><span><\/span><script type=\"text/javascript\"><\/script>");
doc.close();
alert(document.childNodes.length);
alert(document.childNodes[0]);
alert(document.childNodes[1]);
</script>

This is fixed by below, but integrated test still fails:
