Changes

Yes, many MailNews code is misaligned, uses tabs instead of spaces for indentation, has trailing whitespace and what not. If doing stuff in the vincinityvicinity, fine, do the clean up. But don't touch it just for arbitrary whitespace correction, this just messes up the "whodunnit" history in our repository (and you don't want to look responsible for <strike>Blake's</strike> someone else's code, do you?).
