- remove unnecessary includes - expunge all remaining usages of boost::format - able to leave out the expliti string(elm) in output - drop various operator<<, since we're now picking up custom string conversions automatically - delete diagnostics headers, which are now largely superfluous - use newer helper functions occasionally I didn't blindly change any usage of <iostream> though; sometimes, just using the output streams right away seems adequate.
