Title: Don't set all plugin functions as default when kind is specified in use()

Consider:

skimage.io.use_plugin('freeimage', 'imread')
skimage.io.use_plugin('matplotlib', 'imshow')

Currently, the second call replaces freeimage.imread as the default imread function with matplotlib.imread, which is unexpected.
