[RELEASED] for UE4: Complete Sky and Weather System

I’m using version 309 with version 4.10.4 and it works fine.

If you have problem after compiling, remember to copy the files from Epic Games\4.10\Engine\Plugins\TrueSkyPlugin\shaderbin\ to the standalone build - Engine\Plugins folder. If it not exists, create the same folder tree as from the Engine.
