GIF transparency index is always added

[Nadia Alramli]

When an image is saved as GIF the transparency index is always written as 255 even if there is no transparency. In many images there might be not visible difference. But it is possible for parts of the image to become hidden because of this.

Committed and pushed the fix to: https://code.launchpad.net/~nadiana/phatch/transparency-fix
I ran the test suite after and before the changes and compared the results using the script. There are few visual changes. The changes are because P mode is now handled explicitly in 2 new cases (pdf and xbm). Before they were left to PIL to handle them poorly. The transparency fix didn't affect the visual result in the test case images, it just removed the extra transparency index.
