docs: Adds a Notifier to the current environment (binds to existing Detectors in {motionDetectors} variable).
  Checks that the notifier is of {BaseNotifier} instance. Allows to force adding a notifier event if not
  of the correct type, by setting force = true
  @param {object} notifier is the Notifier object to add.
  @param {object} template is the template message for the notifier, in case it triggers.
  @param {boolean} force can be set to true to push the notifier even if not of {BaseNotifier} instance
  @returns {Boolean} true if the notifier is successfully created.
