`tkinter` source and docs use the word 'slave'

I know tkinter is just a wrapper for Tk but this reference to slaves is pretty bad. Maybe it could be referenced as child widgets? Pretty much anything other than slaves.

There are a series of occurrences both in tkinter/__init__.py and the doc. You can find suggestions for replacements in the devguide.
