Minor bug fix.
Fixed bug where views were being rendered twice in the layoutmanager due to setTemplate also triggering a view render.  I changed it so that setTemplate no longer re-renders all the views.  This will mean changing the template will not redisplay existing views.  In the future this will need to be fixed with a different api.
Changed the ssmProvider to call ssmLayoutManProvider.addLayout when a scene is added.  This will make for less config code.
