tiled is a geoserver param

[jfgodoy]

To enable geoserver wms service with geowebcache is needed to pass tiled=true as param, but this is filtered by leaflet.wms :(

Hmm, yes that's a problem. We'll probably need to change the option name - perhaps to untiled with the default of true? A temporary workaround would be to add &tiled=true to your base WMS url, i.e.:

var s = L.WMS.source("http://example.com/mapserv?tiled=true", {
    'transparent': true,
    'tiled': true
});

The ideal solution would be to treat WMS parameters entirely separately from the layer options, but we're punting on that for now for compatibility with Leaflet (see Leaflet/Leaflet#2972).
