Fix #478 Reduce PS Resolution for Large SuperCell

- does not use more than 32KB shared mem in kernel
  (not going to 48KB since some functors might need
   some shared for caching)
- first part (work around) for #469
- reduces the resolution of all phase spaces enabled
  to fit the shared local phase space with the
  setting of longest super cell edge
  (remember: ps is spatial direction * momentum)
