createVerifier() does not use salt given in setSalt()

[tyler-burkett]

I noticed that in Client.createVerifier() the saltBuf is always set to the salt value provided in the srp.generateSalt() callback. This consequently means that any salt set using setSalt() is not used when creating the verifier. This looks like a bug.

Hmm, I see. The thing is, setSalt() was designed to only be used during the login process, not to provide a salt to the createVerifier() process. So in that case, it's not really a bug but poor documentation on my part.

However, the use case where someone would like to bring their own salt during the verifier creation process should probably be supported, so I'll leave this open.
