traffic light model in gzweb

[laitathei]

traffic light model in gzweb cannot light up but it works in gazebo
it seems to have a problem with the emissive tags

this is my traffic light mode script

<static>true</static>

<!-- this pose can be overriden when including the light on another model -->
<pose>0 0 1.0 0 0 0</pose>
