CharacterCorpsePrototype: use of picture/pictures

[Pi-C]

The documentation for CharacterCorpsePrototype tells us that pictures is mandatory if picture is not defined, and that picture is mandatory if pictures is not defined. However, it doesn't tell which will be used if both picture and pictures are defined in the prototype.

According to my tests, pictures will be used in that case. Could you add this info, please?

Thanks for the note. I've adjusted the description of "picture" to make clear it's only loaded if "pictures" is not defined.
