Patch to recognize <graphic> like <imagedata>

<imagedata> is not the only way to include images in a document, there's also <graphic>. It would be nice to support <graphic> too. I attach a patch which tells publican to deal with it in the same way. Seems to work here.

BTW I noticed something odd while reading that part of the code:

                            my $max_width
                                = $self->{publican}->param('max_image_width')
                                || 10000;
                            my $set_width = $node->attr('width') || 0;
                            $set_width =~ s/[^\d]//g;

Ok max_width is 444, and set_width is the custom width if any.

                            if ( $set_width == 444 ) {
                                $node->attr( 'width', undef );
                                $set_width = 0;
                            }
We drop the attribute if the user set a custom width of 444. I don't see why, it could make sense to force a width of 444 if the user changed its max_image_width. But why not, it does not hurt.

                            # Do not override user settings
                            if ($set_width == 0) {
                                $max_width = $set_width
                                    if ( $set_width
                                    && $set_width < $max_width );

Here it gets messy... we test $set_width == 0 so we know it's zero and we know that the test "if ($set_width && ...)" will fail, so this line is never executed. Maybe you wanted that line in the previous test ($set_width == 444) so that the max_width is reduced accordingly to the user specified size.
