- Adding the support for remotely detonating cubes, and cubes signalling their own fizzling, allowed me to remove some ugly behind-the-scenes contraptions in the tutorial room.

OOPS!! Making the last edit using Stylesmod 60s style removed all the plastic tubes and much else. I had to create all that over again. Fixed.

Oops! For some reason, "spawn first cube automatically" was on for a dropper that it was not meant to be. Fixed this.

The initially-oriented laser redirection cube in the lesson can now be respawned if it gets destroyed.

Read here if you want to know how I did it. http://forums.thinkingwithportals.com/post96391.html#p96391

- Warp discovered a way that a suicidal player can trap themselves in the laser lesson; unlikely to happen by accident. Prevented this nevertheless.
- Made the glass panel holes in the laser lesson larger, for easier aiming.
- Adjusted some lighting elements.

Created a glass panel with a hole in it. This simplified the architecture of the tutorial section a bit.

Another update... because of reasons.

(I had a portal magnet upsidedown, preventing lasers from being aligned.)

For some reason, many of the antlines were missing in the previous version. This release does nothing except add the antlines back.

Drats. I just figured out a way to lose the first sphere and not being able to retrieve it. So I added a button to respawn it. Should always do that!
