Changed Eclipse formatter preferences: 1) Use tabs for indentation (I
think this is what we've been using), and 2) Don't format header

Ran cleanup on AtomCache; this time didn't sort members.
Also don't add 'final' everywhere. I think that's probably a little overzealous and intrusive.
Ran more conservative cleanup on AtomCache.
Missed Andreas's recent changes.
