multi-page TIFF writer

[Zachary Pincus]

OK, unittest added: https://github.com/scikit-image/scikit-image/pull/508

Also, BTW, I get the below test failure when I have matplotlib but no PIL installed. I think test_imread_url or the test right before it must be making some incorrect assumptions. (If I re-run the tests after this failure, then also all of the tifffile tests fail, so it seems that some test isn't doing proper teardown of the image loading plugins?)
