Update to Infoclio's styles (for Swiss historians)

Small update to a style created for history students in Switzerland [1]:

* Bug fixes: number of volumes and volume number not separated (leading to "33" instead of "3 / 3"), reports lacking information, repeated suffix in the French styles
* Making use of new CSL 1.0.1 features: duration for films and audio, and dimensions for artworks
