dispatch helpers

createMessageDispatcher creates a message listener which will call a method on the handler argument, based on the contents of the message that's passed from elsewhere. It does this by injecting the (potentially error causing) method into a promise chain, by sticking it inside a custom thenable, which gives us much nicer error handling.
