Multiple lasers only display waste heat for one in editor

If you make a ship that uses multiple stacked lasers (using the "count" slider on the laser module), the waste heat display, including the radiators not removing enough heat warning message, will be displayed as if you only had one laser. If you size your radiators according to that, the result is that shortly after opening fire, most of your lasers overheat and stop firing.

A workaround until this bug is fixed consists in either calculating the total needed radiator area from the waste heat and temperature, or in sizing the radiator area for one laser, and then multiplying that by the number of lasers you have.
