elide the title on a word, and put the output in the README

The seven-day view cut each commemoration at a hard 44 characters, mid-word
and with nothing to say it had done so, which is how 'father of the
Forerunner' became 'father of the Fo'. It now cuts on a word boundary, says
so with an ellipsis, and takes its width from the terminal instead of a
constant, so a wide window shows the whole name.

Also adds a screenshot of the output, since a calendar is a thing people
want to look at before installing.
