feature/Google Maps Scrollwheel

Option to enable/disable Scrollwheel. Implemented as done and tested in a live setup, not tested in this version.
That's true, however if google were to update their code for some reason to do a type match, this would break, and we really have no reason to not follow what their [documentation](https://developers.google.com/maps/documentation/javascript/reference#MapOptions) says that it is expecting. Overall I think this feature could be useful, I just think we should adhere to their strict types they are hoping to see.
