* Merge from Debian unstable.  Remaining changes:

    always have an authentication agent running. To be forwarded upstream.
  - 06-authentication-failure-string.patch: Improve error message displayed
    when authentication fails.
  - 07-use-accountsservice.patch: get user icon from
    accountsservice instead of looking in ~/.face. (LP: #928249)
  - debian/patches/08-fresh-x11-timestamps.patch: use fresh X11 timestamps
    when displaying authentication dialog to circumvent focus-stealing
    prevention. (LP: #946171)
  - Tell the .desktop file for the authentication agent to auto-restart the
    agent in case of failure.
  - add dh --with translations
