Change default terminal type from xterm to vt220.
  If one day Emu supports many term types, it may make sense to default
  to something else such as `emu'
  But for now, the only emulation of wide interest that will cause most
  people to want Emu at all, is the vt220 emulation,
  only developers would want types `emu' or `xterm', as we already have
  the real xterm, & `emu' mode is of academic interest.
