Better splits; don't count everything as a word

[camilstaps]

At the moment, we only split the text on spaces, but we should also split on ־ and ׃ and possibly more signs.

Furthermore, some things should not be considered a word:

• פ and ס at the end of a verse
• ׀ (still unclear to me what this actually means)

And then ketiv-qere should be handled better, e.g. (Ps. 119:161) [וּמִדְּבָרֶיךָ כ] (וּ֝מִדְּבָרְךָ֗ ק) breaks as four words, of which ] and ) are part. The characters [, ], (, ) and כ and ק in this context should not be considered part of a word.
