Vue2leaflet: Enhancement: Expose property to enable/disable the zoom button layer.

[InfoSec812]

As a developer creating an app which tracks the user's current position on a mobile device, I would like the ability to disable the zoom in/out button layer on the map view. The attribute in the Leaflet project is called zoomControl and should be relatively easy to expose. I will try to submit a PR shortly for this feature.

You can do this at the moment by just using :options={ zoomControl: false } on the LMap component.
