Title: Highlight boundaries

Improve `skimage.segmentation.visualize_boundaries` with support for grayscale images and user-specified colors.

Also, rename `visualize_boundaries` to `highlight_boundaries` to make it clear that the function doesn't actually plot a visualization but instead highlights boundaries directly on the image.

The renaming required deprecation of the old name, so a `@deprecated` decorator was added also.
