Nicholas Nethercote d225f7151b Bug 1400460 - Rename nsIAtom as nsAtom. r=hiro.
(Path is actually r=froydnj.)

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

MozReview-Commit-ID: 91U22X2NydP

rename : xpcom/ds/nsIAtom.h => xpcom/ds/nsAtom.h
