When I say "sun halo" I do not mean the atmosphere, but the "big halo"
which is now calles just textures/halo.png. You cannot see it with the atmosphere on.
So I am not sure what you have seen.  I suggest turning off landscape and atmosphere.

To me nothing is evident, except that the sun halo is not visible during the
2 seconds of changing from one planet to another. If you see some bugs,
please tell me. You can slow down the transitioning process by incrementing
the value "2000" in Observer.cpp.

I know that there is no such GUI interface, and I have decided that I will not implement it.
Remember that I also did not implement the tui for changing the home planet, I just made
the function itself. It is just because I am a bad gui programmer, and because I have still
other things to do. I only made the smooth transit function because you said, you would like
it, and because I said it is not that difficult.
