feature: new options for draganddrop

[jokd]

Fixes #1792
New options:

"zoomToExtent": true, // Adds zoom to layer option for the layer, default true
"zoomToExtentOnLoad": true // Zooms to layer extent  when loaded, default true

I tried this config

   {
      "name": "draganddrop",
      "options": {
        "zoomToExtent": false,
        "zoomToExtentOnLoad" : false
      }
    }

but I got both option on, it zoomed to feature and menu option was there.
