any object part labels so that the flipped dataset has the same average part

--flip.  However, most people flipping a dataset with part annotations will
want to use --flip.

* imglab: select next/previous image with 's' and 'w'

* imglab: make 'w' and 's' keys behave like UP and DOWN keys; add 'about' text

because it's a much less stressing hand motion to hit END that i in most cases.

histogram is equalized or unmodified.  This way, if you are looking at
particularly dark or badly contrasted images you can toggle this mode and maybe
get a better view of what you are labeling.

Changed from ctrl to alt because otherwise it's easy to accidentally hit ctrl up and jump when you don't meant to while pruning an image list.

* Add option --rm-other-labels to imglab

* Add support for comma separated list of labels

it simply partitions the data and is an invertible operation.
