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.

Added a wrapper around ndimage's Gaussian filter
...
This version of the Gaussian filter
* uses 'nearest' as the default boundary mode. This can be discussed,
but I had the impression that for images this is the most relevant
mode ('extending' boundaries)
* has a `multichannel` keyword, so that each color channel can be
filtered separately. For now no attempt is made at guessing whether
the image has color channels or not.
