Super Star Trek TO-DO list

* The time machine switch.  Specify a year, get only the features that
  then existed.  (This would be partly so people can try the original
  non-"super" version Matuszek and Reynolds wrote.)

  Dave Matuszek tells me that SRSCAN, MOVE, PHASERS, CALL, STATUS,
  IMPULSE, PHOTONS, ABANDON, LRSCAN, WARP, SHIELDS, DESTRUCT CHART,
  REST, DOCK, QUIT, and DAMAGE were in the original non-"super" version.

* Write a curses-based interface.  Shouldn't be hard, all output goes through
  prout/proutn/prouts so we can split the screen into two panes with the upper
  one for the charts.
