- Add "Intensity" property for dynamic lights in GLDEFS that will multiply the brightness of the light, useful for overbrightening/underbrightening a light.

Browse source 
- Also add an "intensity" parameter for A_AttachLight in ZScript.

Note that for any kind of light overbrightening to do anything at all, one of the unclamped LightBlendModes in MAPINFO must be enabled.
