This patch uniformizes warning messages. I used the most common style already present in the code base: * Capitalize the first word. * End the message with a full stop. * "Rails 5" instead of "Rails 5.0". * Backticks for method names and inline code. Also, converted a few long strings into the new heredoc convention.
