Elm(ish) onClick Event/Function Attribute

[nelsonic]

In order to simplify event listeners in our TEA example apps,
I'm thinking that adding an onclick attribute to a given node and passing in the signal(action)
is the simplest way of keeping the view declarative.

This will be useful for both "delete" a todo item (which is a button) and incrementing a counter.

• add_attribute([function]) >> onclick=signal(action)
