WMS params cannot be changed at runtime

[greeninfo]

Once a WMS layer is constructed, no public method is available to change the WMS params.

The following patch adds the new methods setWmsParam and redraw()

setWmsParam: function (name, value, redraw) {
    this.wmsParams[name] = value;
    if (redraw) this.redraw();
},

redraw: function () {
    this._reset(true);
    this._update();
},

For some use cases, this is absolutely vital: merging multiple layers into one WMS request, adding vendor params or CQL.

You're right, thanks for the suggestion - will be added!

Just pulled the source to get this fix and leaflet.js is out of date. Running jake fixed it right up through.

Yep, I'll update the build.

setParams() would be nice on L.TileLayer as well. Why not make it part of L.TileLayer and WMS could inherit or extend it behaviour? Thank you for considering.
