Add map bounds to available data.

I am integrating google-map with an elm project and at a certain point I needed to have the map bounds available without callbacks.

can't help thinking the Elm stuff should go in a seperate PR with a full explanation of why it was necessary and the consequences for non-Em users.

But beyond that I really hope someone gets round to reviewing this as this is an important feaure

The issue here is not related to Elm. Elm only made it surface. The situation is that markers can be added an removed to the DOM. The HTML DOM allows that and webcomponents honor that. The fix here is to check for the existence of the google.maps.Marker instance and not the existence of the google.maps.Map when we are binding/unbinding marker related events. I can open a new PR, but I thing the situation is simple enough.
