Title: Determine zoom in TileLayer.Canvas#_loadTile rather than expecting a zoom argument

TileLayer.Canvas#_loadTile expects a zoom argument when called from TileLayer#_addTile, but the zoom argument is not passed anymore (looks like it was removed in c50aaabd). This adds a call to _getZoomForUrl to determine the zoom.
