Customized blockquote handling removes elements

[greatislander]

It looks like the changes made to htmLawed's <blockquote> handling in this package have caused a regression in 2.2.

Steps to Reproduce

1. Pass the following HTML through Htmlawed::filter() with default configuration:

<blockquote>
  <p>Line 1</p>
  <p>Line 2</p>
  <p>Line 3</p>
</blockquote>

Expected Result

The markup is left unchanged.

Actual Result

The <p> tags are stripped from all but the first <p> within the blockquote.

<blockquote>
  <p>Line 1</p>
  Line 2
  Line 3
</blockquote>

Thank you for reporting this issue!

Unfortunately the unit tests won't pass because we have slight differences from the original library but if we put 'blockquote' back into $cb.
Adding it to $cF does the trick though!
