Allow sequences of monologues to be queued up at once.
Allow sequences of monologues to be queued up at once.

show_monologue can now take a list of monologues, each of which will
play in sequence. There's also a callback for when all the monologues
have been processed.

If a monologue is still on the screen when another starts, the first
will be closed.
