28b818974e Allow to save tiff stacks from separate images 
This is a quick solution that will allow to save tiff stacks from
separate images, e.g. from Numpy arrays.
Previously, tiff stacks could be saved only from multiframe images.
This behavior is similar to what is possible now with GIFs.

Note however, that for correct results, all the appended images should
have the same encoder{info,config} properties.

Example:

import numpy as np
from PIL import Image
a = np.ones((100,100,100), dtype=np.uint8)
imlist = []
for m in a:
    imlist.append(Image.fromarray(m))

imlist[0].save("test.tif", compression="tiff_deflate", save_all=True,
               append_images=imlist[1:])

(Should result in a 100-frame, 100x100 tiff stack.)

caf53b05ec Fixes TIFFImagePlugin ICC color profile saving. 
In the TIFF code saving icc_profile is conditional on tag_v2 being set which doesn't make sense to me. I believe this is merely an indentation typo.

I've been trying to save TIFFs with im.info['icc_profile'] set and compression=raw, but unfortunately this results in TIFFs without ICC color profiles.
With the attached patch TIFFs with said conditions will be saved with the profile set in im.info['icc_profile'].

Note: There are a number of different conditions that need to be met for code to succeed in saving with the profile since it branches between using libtiff and ImageFile._save(..), and the libtiff code does not currently save the ICC color profile.
For instance setting compression=tiff_lzw will result in using libtiff and no profile will be saved.
