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.

9fa6634f4d Partial fix for #1597 
Haven't excercized all of the metadata that we're allowing yet,
and there's clearly still something up with Arrays, as one
of them is still crashing and making it impossible to save a
palette with a libtiff image.
