Review request for mesos, Benjamin Hindman, Charles Reiss, and Jessica.


L59 should fix the start mpiexec problem


Some updates to point out:
  -> 'mpdallexit' should terminate all slaves' mpds in the ring. I moved 'driver.stop()'
to statusUpdate() so that it stops when all tasks have been finished, which occurs when the
executor's launched mpd processes have all exited.
  -> Didn't remove cleanup(), and added code in shutdown() that manually kills mpd processes.
They might be useful during abnormal (cleanup) and normal (shutdown) framework/executor termination...I
think. cleanup() still terminates all mpd's in the slave, but shutdown doesn't. 
  -> killtask() stops the mpd associated with the given tid. 
  -> Task states update nicely now. They correspond to the state of a task's associated
mpd process.
  -> Included additional info on how to setup and run MPICH2 1.2 and nmpiexec on OS X and

This addresses bug MESOS-183.
