[Image-SIG] Patch for loading .tga files

[Alexey Borzenkov]

Hi everyone,

As a follow up I found a really small bug with loading .tga files
where loader didn't accept 1-bit depth black&white files. See the
patch below, but I've also appended it to patch at
http://snaury.googlepages.com/Imaging-1.1.6-df-tga.patch (which
requires http://snaury.googlepages.com/Imaging-1.1.6-df-bgr.patch)

P.S. I wonder why my previous two letters didn't get thru to the
mailing list... x_x
