Fixes the debug netevent packing error by keeping the mStart value as it's proper 0-1 range until it gets to the client, using a temporary world-space var for finding strike target objects in the radius.

Also add a checker for if there is a texture or not set for the lighting bolt. If it use, set the stateblock description to support it and set the texture, if not, only utilize the color blend.
