add a puzzle game with...

Original commit message from CVS:
* configure.ac:
* gst/games/Makefile.am:
* gst/games/gstpuzzle.c:
add a puzzle game with...
* gst/games/gstvideoimage.c:
* gst/games/gstvideoimage.h:
... full colorspace support (that includes YUV9 and RGB16)) stolen
from videotestsrc and made into something that would be a nice
library for a lot of other plugins.
