- Tagged the icons with a bottom-left icon to diferentiate easier from the vanilla catwalks.

- Optimized the main models, lower overall polygons;
- Added a really low-poly LOD model at 30m for each block;

- Added 5 blocks, a 4-button catwalk rail and the vanilla catwalks with smaller collission models;
- Fixed the contour texture of the small button not being colored with the icon;
- Made the original block's catwalk full size again (visually) and added mount points on the side;
- Added a new "Elevator Pad" block category, along with the newly added blocks to it and to the assembler production;
- All elevator catwalks overwrite the vanilla catwalks position in the G-menu (you can still find the vanilla ones in the menu and use them).

- Added the ability to place the block on a piston that's surrounded by blocks.

First public release.
