TUT: use defaultPatch for naming instead of explicit Default_Boundary_Region

- tutorials based on squareBend used Default_Boundary_Region explicitly
  defined since they predated the defaultPatch renaming (2008).
  The name 'Default_Boundary_Region' was for convenience as the default
  name when converting to PROSTAR or CCM formation, but can now be
  changed to something more generic.

- define wall boundary conditions for squareBend using a general regex
  to allow future splitting of wall types by name.
