[Image-SIG] Patch for SunImagePlugin

[Charles G Waldman]

I could have sworn I've submitted this patch before, but
the bug is still present in PIL 0.3b2.  SunImagePlugin
fails to load Sun image files with a palette, because
"ImagePalette" is undefined in the scope of SunImagePlugin.
As is so often the case, the description of the problem
is longer than the patch!
