images were obtained from the US Naval Observatory; see here for the
statement that they are public domain (item #2):
http://www.usno.navy.mil/privacy.shtml

Updated README.images to more accurately state that NASA images are public
domain (we had classified them as "free with credit given", but giving
credit is a courtesy request, not a requirement).

Fixed bug where size of inline images changed with orientation.  This was
especially noticeable while tracking the Moon.  See SkyMap::drawPlanet()
for details.

Images are less ugly when rotated now, because we scale first, then rotate
(we used to rotate, then scale).  Added KSPlanetBase::scaleRotateImage()
to handle this.

Don't forget to run 'make install' to install the new Moon images.
