add image comparison behave tests

[KatrinPoepp]

Pytroll image comparison dev behave tests as PR. This method of code transfer was proposed by Martin Raspaud.
Documentation for the behave tests will be provided with the rest of the project code.

[gerritholl]

The branch for this PR includes 322 MiB in data (8 PNG files), added in commit 1367072. We should probably upload those files somewhere (zenodo?) and then include code to download them on-the-fly, as to not pollute the git repository with large binary files. This may need rewriting the commit history?

[pnuu]

Yes, I think getting completely rid of the images from the repo requires rewriting the git history on force-pushing.

[gerritholl]

If we remove the images in a dedicated commit, then squash the commits before merge, would that be enough to remove the images from the git history?
