Bridge and tunnels layer order needs fixing

[sensescape]

Noticed layer order is wrong: http://maps.stamen.com/toner/#17/55.62918/12.57752

Highways are ordered correctly.

To draw tunnels differently, add something along the lines of:

  [is_tunnel='yes']
  {
    ::outline
    {
      line-dasharray: 4, 4;
      line-color: #f0f;
    }
  }

or:

  [is_tunnel='yes']
  {
    line-opacity: 0.5;
  }

immediately beneath:

.roads[kind='major_road']
{
<paste here>

is this fixed?

Yes.
