create button component

This might actually be two different components. A plain button component without any text, and a text button component that utilizes the text component (#14) to display some button text. Buttons usually have text on them so the text button will likely be "Button" and the plain button could be something like "Clickable".

Abstracting out the clickable functionality of the button into a "Clickable" component would allow creating things like image buttons and the like.

This really should have anything to do with text. We just need a clickable component that has no visible UI. Then we can create buttons and text buttons by composing clickable with other components.
