Support leaflet panes (1.0 feature)

[a1an77]

Hi, in my project I am using leaflet panes http://leafletjs.com/examples/map-panes.html
It turns out that this plugin does not consider them at all, hence the paths get drawn in the custom pane while the text is drawn on the overlay pane. This leads to paths been shown above other features while text gets drawn below them. It would be great if the plugin could check on which pane its path gets drawn and put the text on the same one accordingly.

I just created a pull request with changes from my repo. I added the 'pane' option explicitly even though getting it from the layer where the path lies would be even better. This does the trick for now anyway.

Anything preventing this from getting in?

Don't know how it looks in your case, but I even get errors like:

TypeError: Cannot read property '_container' of undefined
    at NewClass.setText (leaflet.textpath.js:78)
    at NewClass._textRedraw (leaflet.textpath.js:43)
    at NewClass._updatePath (leaflet.textpath.js:36)

Can this PR be merged?
