permutedims for vectors and matrices

[mcabbott]

Before:

julia> permutedims(SA[1,2,3])
1×3 reshape(::SVector{3, Int64}, 1, 3) with eltype Int64:
 1  2  3

julia> axes(ans)
(Base.OneTo(1), Base.OneTo(3))

julia> permutedims(SA[1 2; 3 4])
2×2 MMatrix{2, 2, Int64, 4} with indices SOneTo(2)×SOneTo(2):
 1  3
 2  4

After:

julia> permutedims(SA[1,2,3])
1×3 SMatrix{1, 3, Int64, 3} with indices SOneTo(1)×SOneTo(3):
 1  2  3

julia> permutedims(SA[1 2;3 4])
2×2 SMatrix{2, 2, Int64, 4} with indices SOneTo(2)×SOneTo(2):
 1  3
 2  4 

Unchanged are all the cases taking perm, discussed in #806.

julia> permutedims(@SArray(rand(1,2,3)), (3,2,1))
3×2×1 MArray{Tuple{3, 2, 1}, Float64, 3, 6} with indices SOneTo(3)×SOneTo(2)×SOneTo(1):

I'm not too sure what should happen for MArrays or SizedArrays.

Sorry for the delay but could you bump the patch version? I'm going to merge this soon and tag a new release.
