update 2.1

yo yo yo yo yo its ya boy with another update here. this update adds a new HD skybox as well as revamped terrain. it's only available for the regular version because I screwed up and deleted both of them earlier, so I remade the regualr version (in the 40 minutes between uploading cinematic version and this) and posted it now with the updated, but I don't really give a crap about the cinematic edition
