Add mdl as dependency

[davidpelayo]

I would rather go for adding the mtd dependency in the project and require only the select input javascript. This way you don't need to maintain manually the select input from mtd manually.

What do you think?

@davidpelayo I'm not sure I understand what you mean

Never mind. I misunderstood something at the time I was writing it.
