Handle gmail_quote div in emails created by clicking the Reply button in gmail

@fiatjaf this one should be fixed. At least for Gmail. The edge case @jeremyschlatter found aside - not sure how we could fight this one. It will be solved when we stop looking for html tags completely and improve on html to text, strip text quotations, remove corresponding html tags algo.

So far I just made a change not to handle <blockquote> as an indicator of quotations if it has gmail_quote. Since Gmail uses divs with gmail_quote class to indicate quotations.

It's not only that, when you insert a quote yourself, using the Gmail formatting tools (suppose you're quoting Shakespeare, for example), you'll get something like

 <blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
  <div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">
   My name is William Shakespeare.
   <br/>
  </div>
 </blockquote>

and it will be stripped out, even though it wasn't part of the previous email and is standing there right in the middle of your message.

But I also don't have a suggestion on what should be done.
