When armature is selected for custom shape of a bone, we run into stack overflow due to recursive calls. To prevent this situation, exclude armature object type from the custom shape list. This also clears the `pchan->custom` pointer after loading/linking a blend file. Otherwise a linked Armature object can still be assigned indirectly, by renaming objects in the library file.
