Run Emacs and Lisp from 'login.ifi.uio.no'

The IFI student machines are currently being upgraded from RHEL 5 to 6 (including the desktops in Assembler). Unfortunately, there's some lag in this process in terms of getting all the software we require for inf4820 in place. In the meantime, you can log on to a RHEL5 terminal by 'ssh -Y login.ifi.uio.no' and then run Emacs and Lisp from there.
