BUG: add signed flag to chars
...
Sign of char is undefined and there are numerous places where its sign
is important. Fixes tests with -funsigned-char.

Fixed some issues with the new windowed_histogram function in filter.rank.
...
It used to be able to output uint8 histogram, whose max pixel counts of 255 could easily overflow. Addressed by limiting the output type to float.
Normalized histograms are now generated, otherwise behaviour is unpredictable at boundaries or when pixels are not permitted by a mask.
The new optional n_bins parameter allows the caller to specify the size of the histogram generated. Having it fixed to image.max()+1 could result in feature vectors being shorter than desired just due to a value not being used in an image.
An example has been added to the docs, that demonstrates the application of windows histograms in object matching; a single coin is extracted and found by chi squared histogram matching.

Modified rank filters package so that the _core function in core.pyx outputs to a 3D image, permitting the generation of images with arbitrary size feature vector pixels. Implemented windowed_histogram that generates a windowed histogram of an image.

Bug fix: nbins can be >256 in threshold_isodata
...
The threshold_isodata function created an arange of values up to the
number of bins, but gave it type np.uint8, limiting the number of bins
to 256.
Fixes #1085 .
