title: sublime text 3 on mac os not keeping project open
body: <p>I'm using sublime text 3 on mac. Whenever I've had a project or folder open and closed the window (not quit the app) it would remember where i last left off, and open my last window. I noticed now when I close the window it gives me a blank document. I have to go browse to open the project. Is there some setting I'm missing?</p>
  
  <p>EDIT:  okay I guess this is because the application hasnt really exited when i hit the red x.. its still running but i just closed my tabs.  is there any way to make sublime text quit when all its windows are closed?</p>
