Ichthyostega 2c20d407fc mass clean-up: adapt usage of std::cout pretty much everywhere 
- 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.
