Juan Nunez-Iglesias ea1566fffb Fix image dimension sanitizing at function start 
`np.atleast_3d` will add a singleton dimension at the end of an array
if needed. This is not the correct thing to do if `multichannel=False`
based on the subsequent lines. If the input image was 2D with shape
`(40, 50)` and `multichannel=False`, then `np.atleast_3d` gives it
shape `(40, 50, 1)`, and then, because `multichannel=False`, the rest
of the code gives it shape `(40, 50, 1, 1)`. This results in the final
returned array having shape `(40, 50, 1)` instead of the desired
`(40, 50)`.

This commit fixes that and updates the test to detect this failure.

Juan Nunez-Iglesias 35e8ad2ccc Allow grayscale input images to SLIC segmentation 
There is no reason for SLIC to be restricted to colour/RGB images. I
have added a few lines that allow single-channel input.
