labs 2/6 done

tech: chain reaction - blocks caught in explosions, explode
tech: shock wave reduces explosion damage by 30% (was 40%)

slime hazards now draw themselves in hazard.query()
I updated all the maps to remove hazard.draw()
    but maybe I missed one let me know if you find a buggy slime
laser hazards also draw themselves in hazard.opticalQuery()

2/6 rooms for new level.labs() are completed
