Brecht Van Lommel d579ea2901 Fix #34863: bge.render.makeScreenshot from Blender was only saving PNG files,
while the docs said it followed the settings in the Output panel, other file
formats work now.

Benderplayer still only saves PNG now as documented, but I cleaned up the code
there to reuse existing imbuf functions rather than using own libpng code.
