Label internal nodes

[stephenshank]

Add option to display internal node labels.

This could be implemented by providing a custom node styler. I think you could modify the following line to check the setting and to apply this internal node styler before applying the custom node styler:

phylotree.js/phylotree.js

Lines 2337 to 2341 in bfb49ba

	if (node_styler) {
	nodes.each(function(d) {
	node_styler(d3.select(this), d);
	});
	}

If you'd like me to try to write that into a pull request, let me know!
