Changed design a little

Made the grate platform higher to avoid tossing the cube up to the other side.

After watching three Youtube videos where it took five minutes to figure out how to get across the water, it became apparent to me that people tend not to look at the brightly colored antlines showing what a button does. The floor button in front of the entrance now only deactivates the laser field.

Changed the one-way grate bridge so the player grabbing the cube cannot immediately return to the other side with it.

- Changed pedestal button for angled panel to use antline visibility, so it's easier to know what it does before pressing it
- Moved floor button in front of entrance closer to the center, to make it more obvious that it has to be held down to activate the angled panel
- Changed faith plate to one-way grate bridge, to A) make getting the cube more convenient, and B) make seeing the portalable floor easier from the other side (so to speak)
- Moved laser reciever for the alternating panel bridge to make jumping back easier
- Changed lighting in various ways
