Not compatible with most recent versions of leaflet module: fatal errors in LeafletCountryFormatter

I have tested this module with the most recent versions of leaflet module (first with leaflet 8.x-1.0-beta16 and then 8.x-1.0-beta18) and found that it is not compatible: it generates fatal errors in the functions LeafletCountryFormatter::settingsForm() and LeafletCountryFormatter::viewElements(). In debugger I found the following bugs:

1. The line $elements['zoom']['#options'] += array('auto' => 'Auto') in settingsForm(() generates fatal error because there is no $elements['zoom']['#options'] anymore in the $elements array.

2. The call leaflet_render_map() in viewElements() generates fatal error because there is no such function anymore in leaflet module.

3. To show the map properly after fixing the 1. and 2. I had to change the code that gets the zoom parameters from the settings: instead of $settings['zoom'] it has to be $settings["map_position"]["zoom"] and similar ones for minZoom and maxZoom.

I have it functional now after the fixes, so I will create a patch and post it here in the thread.
