patch applied (cabal-install): Don't echo when prompting for the hackage upload password.

Thu May 1 14:44:56 PDT 2008 Duncan Coutts * Don't echo when prompting for the hackage upload password. Fixes ticket #268. And use newtypes for the username and password, just to be more sure we're not mixing them up with other strings.
