Environment Art: ny_pier area

ny_pier's environment art is 95% done, and implementation for its' usage for Story Mission 001 is also almost done. Please hang on tight for this mission in the next Bleeding build soon!

Some polish items that will be added later, after getting the mission into a build:
-vista level art assets (buildings and features way in the distance, out of the playable area)

-non-placeholder ocean shader
