permute of a scalar

[David Bateman]

If 

a=1; b = a'; 

is legal, then I think so should be

a=1; permute(a,[2,1]);

that effectively does the same thing. However, as permute is not
defined for scalar values we get a gripe_wrong_type_arg. The patch
below adds the permute function for scalars. However, it doesn't check
the validity of the arguments and just returns the scalar value
itself. The Matlab version does check the indexing vector when called
with scalars, but this doesn't make all that much sense.

Cheers
David
