    bitbake: toaster: add started property to Build
    
    Add a property to the Build model which records whether
    the BuildStarted event has occurred for the build.
    
    The proxy for this event is the presence of variables recorded
    against the Build: as the buildinfohelper only saves variables
    when the BuildStarted event occurs (as the variables aren't
    available on the bitbake server before that point), we can
    tell whether BuildStarted has happened by counting Variable
    objects on the Build.
    
    This can then be used to determine whether a Build "properly"
    started, enabling a different dashboard display (left-hand menu
    hidden) if the build didn't record any useful information (e.g.
    if it had a bad target).
