feat: Complete row height implementation

Browse source 
Now all parts of spreadsheet respond to the -F <fontsize> command
  line argument in fteapot, and row heights are computed in terms of
  the resulting character size.

  There is a new menu option for setting row heights in fteapot.

  Documentation is updated, and keybindings are made more uniform between
  teapot and fteapot and more fully documented.

  Resolves #57.
