Storeria size fix & DDS

I've accidentally overlooked the scale of this ship, and realized it after it was merged. 
So this one fixes it, and adjusts stats too. With this, Storeria will be on par with the Deneb in terms of capacity, but it lacks atmo shielding mount, and has worse maneuverability, even with it's lighter hull. You don't want to land her on Earth if loaded.
Also I realized that the textures weren't converted to dds, so here they come also.
