Leaflet

0.51

- Generic Toolbar class - used by Zoom. Perhaps can use for "Fit" button? - fitBounds - method accepts "padding" argument. Useful for "Fit" button - LayerGroup.getLayers() or hasLayer()- new methods, may allow me to move LayerGroup settings to "Settings", so they will take effect also in List and Calendar views. - various improvements to Zooming UI
