Add default path to menu

[lehkost]

There is a hidden default path through the almanac that follows the multiples of 5. On the first throw, segment 5 appears as a possibility; on the second throw, segment 10; on the third, segment 15, and so on. In the printed book, all of these segments are marked with manicules, represented in the TEI file as subtype="manicule-{left,right}". At the moment, three subtype values are missing (180, 270, 415): two were simply omitted from the file when converting and were just added via PR, while one is absent from the printed book itself.

We could therefore implement this default path as the sequence 5, 10, 15, 20, …, 1000 without checking if manicules are present.

In the interface, we could present the additional option as follows:

Stück generieren

**Entlang der Fingerzeige**
Kürzestes (Wörter) etc.

Generate Play

**Along der pointers**
Shortest (words) etc.
