Exit animations for Mithril components: provide controllers with an `exit` hook which will trigger when the component disappears from the virtual DOM (but before it's removed from live DOM), locking the draw process while you perform animations.
Mithril consumes m.component and returns fully-formed virtual DOM, meaning Exitable never gets the chance to hook into its controller. More patching needed.
