removed the portal outlines

- fixed a design flaw in the chamber where you could get a weighted sphere by standing on a cube instead of using a platform to get to the sphere

- added a noclip prevention

fixed a visual bug where the blue/orange portal from the gun was rendered on top of the world portal even if it was behind it
