Converts all necessary << outputs into the to_chat() macro. (#6076)

This PR will lead us towards the Promised Day, for in its wake there shall be much celebration and ecstasy as this world becomes a world suitable for developer hegemony. The first strike is thusly;

All << is converted into to_chat().
