Use svg icons from material ui instead of the font icons

This way it is not required to import the icon font

For me the best way would be to leave flexible the way of the passage of icons, example if you want to use another source of icon (http://react-icons.github.io/react-icons/), one way of this would be to accept a react element rather than just a string identifier.
