Implements 'no boundary condition'. This can be used to
inform the Boundary thorn that this variable should have
boundary conditions applied to it, but then not actually
apply any local physical boundary condition. This is
useful e.g. if the physical boundary is being updated in
some other manner, but the symmetry boundaries should be
updated normally.
BndNone is also used as a dummy local physical boundary
condition, when the true physical bc is non-local.
