Added new LightGameObject. Added new shader. Numpad 4 for new shader,
does not work as of now.

small bugfixes
Crash free but no working lights
Partial working but still BUGGY

FX file is problematic (AdvancedLighting)
Fixed lighting, improved lights

Multiple lights work, limit@10 for now. Additional parameter,
light.power. Scale of 1-10+ directly affects the lights brightness.
light.intensity changed to work with the same scale. Both default to 1.

Old lighting algorithm made for a wide soft outer edge and  a pretty
much evenly lit core, which was honestly butt ugly. Current algorithm
has no distinctive edges, but is maybe a little bit to even.
