-- wrote new greetings, new greeting responses, and new internal variations within existing greetings/greeting responses.
-- characters are now generated with 2 greetings and 2 greeting responses (instead of just one each).
-- when a character says a greeting line or a greeting response, the game now reprocesses that line so that the character says a new variant of it the next time it's chosen for dialogue.
-- tweaked the weights of certain different types of dialogue for determining a character's dominant personality trait.
-- characters now adopt the Sad facial expression when engaged in the nighttime activity Worry.
-- created a new "Crying" facial expression, in which a character's mouth is turned down and their eyes are both shut tight.
-- fixed an issue in which characters' attack lines were not being used in determining that character's dominant personality trait.
-- fixed an issue where cleaning characters would continue to give the player low-food warnings night after night even after food stores reach 0.
