Cleanup pylint issues

This changeset also brings a couple of changes:

   * rrheaders and rcheaders are dropped from html_writer.Table's constructor.
     They weren't used at all and it was dead code. This simplified some
     if statements.

   * _is_attribute_property is used to look for a property assignment
     instead on relying on a different implementation.
