Add scikit-image

It installs.

I fixed lots of different errors, but this one still remains, when using it on scipy 2015 tutorials, the following code needs to work (this is called inside scikit-image):

In [3]: from PIL import Image

In [5]: a = Image.open("images/spice_1.jpg")

In [7]: from io import BytesIO

In [9]: b = BytesIO()

In [10]: a.save(b, "PNG")

    204                 seek(o)
    205                 try:

    421

IOError: decoder jpeg not available

Note that PIL now links with openjpeg correctly (the commits above make that work):

I reported the error upstream: python-pillow/Pillow#1338
