issues auto generating rna docs

- add a warning when an operator name is NULL, set it to a dummy name to prevent crash. POSE_OT_constraints_clear had its name commented (not sure why)
- rna_Object_parent_type_itemf wasnt checking for context being NULL, needed for docs else it crashes.
- bpy.ops.add/remove didnt show up in a dir(bpy.ops)
