/**
 * IMConfirmation has a single binding "confirmed". If the response from the IM buddy matches any of a set of common
 * "yes", "no", etc words, confirmed is set to the appropriate value. If neither a yes nor a no word is found, confirmed
 * is set to null. You should bind this to a Boolean rather than a boolean so that you can detect the third state
 * properly and re-ask the question.
