title: React - what is the alternative for raised-button in raised-button?
body: <p>I need to add a button with github icon which can be done easily through RaisedButton in material-ui. But I have a beta version of material-ui and seems like it does not have raised-button. 
  What is the alternative for this? Is there something similar in beta version of material UI? 
  (Note: I cannot move to using v0.x of material-ui) </p>
