Tomasz Kapuściński 33b7c893cb Allow length of the light direction vector to influence strength of the light source. 
This fixes the issue with objects and terrain being darker than they should be. As it turns out, most levels have not normalized light direction which happens to make light brighter and this is the expected result. To keep in line with GL14 engine, newer engines should use the length of the vector to make light brighter.
