Title: Add a zoomslider control.

This pull request adds a zoomslider control to the library.

The control has a default css which can easily be overridden to allow for custom styling as the example shows. The initial position of the thumb matches the resolution of maps view and updates itself whenever the resolution changes. While dragging the thumb the resolution of the map gets updated instantly.

Please review.
