Okay, here's the real merger!
Hopefully, I got it right this time.

Old commit log:

Merging Harry's OpenGL branch into trunk!

Yippeeeee! Now everyone can have the OpenGL'd KStars!

I must congratulate Harry on writing such beautiful code.
I really like the way this stuff works now.

There are a whole bunch of *regressions* introduced by this, which Harry has summarized in an earlier e-mail to the mailing list, which I hope, can be fixed at least to some extent before release.

The GL version is much more smoother and nice on my machine.

Also, this has NOT been tested to compile! I'm going to test it immediately after this commit, because I found it convenient that way.

Expect follow up commits to fix compile errors.
