Enhancement: Count word frequency differently

[benjaminpick]

Hi,
I like the bar diagram that shows how often the word/strongsNumber appears in each book. However, if the word is twice in a verse, it is only counted as "1x". Could you add a option in the Search options "nb of verses found / nb of word occurrences found"?

(I am thinking of doing it myself and then sending a pull request, but it will take some time until I come to it.)
