command-namespace: use `::` are the command separator
This was discussed on the mailing list / phab and `::` got a couple of positive
feedback.
I dediced to not introduce automatic folding of `::`, I feel like it make sense
for `-`, but I like the expliciteness of `::`.
So I am adding alias for backward compatibility.
