JWeezy Construction Store Category

I added a whole bunch more options for the placeable track, including new inclined and declined curves and a lot more. All things I needed for my new map build haha. SO I finally got around to adding my own store category in the placeables section. Currently I have it separated into straight, curves, misc track, track extras and trenches. I havent updated the trenches yet so that one will be empty, but all of the track is updated and in their proper category so enjoy! I will update this and add categories as necessary.
