/*
  lib.getWallet(cb)

  - Creates ~/.bot18 directory if it doesn't exist
  - Creates an anonymous, unencrypted Salty wallet at ~/.bot18/id_salty
      (used for verifying downloads from ZalgoNet)
  - Prompts for ZalgoNet email/password at first startup,
      requests an auth_token from ZalgoNet, and
      caches it at ~/.bot18/auth_token
  - Subsequent API calls include auth_token in headers,
      to bind to the associated user account and claimed codes.
