improve the example character yaml format - use multiline blocks

multiline blocks make the input much cleaner and simpler, particularly for the example_dialogue. For the greeting block it can kinda go either way but I think it still ends up nicer. Also double quotes in context fixes the need to escape the singlequote inside.
