This makes a breaking change to the EventHandler such that it can also return a
tea.Cmd. Today the models that are returned from the handlers are meant to act like factories, returning only newly created models, which processing downstream will callInit()on the models to get anytea.Cmds. However, if you are looking to respond to an event on the bus that will not create a new model to be managed by downstream processing but instead a new model that will be subsumed into an existing model, there isn't a way to communicate the subsumed model'sInit()commands.This PR changes this behavior by allowing for event handlers to optionally also return a
tea.Cmdfor new models that are not returned by the handler to.
