Until now, the template type checker has not checked any of the event bindings that could be present on an element, for example ``` <my-cmp (changed)="handleChange($event)" (click)="handleClick($event)"></my-cmp> ``` has two event bindings: the `change` event corresponding with an `@Output()` on the `my-cmp` component and the `click` DOM event. This commit adds functionality to the template type checker in order to type check both kind of event bindings. This means that the correctness of the bindings expressions, as well as the type of the `$event` variable will now be taken into account during template type checking.
