[Bf-python] Some bpy.types Custom Properties Are Read-Only

[Khalifa Lame]

Ah, that explains a lot. An error message during prop creation would have
been very helpful. So what options (if any) do I have? Verts, edges and
faces do have individual properties like bevel and crease weights. How were
those properties created? Can I somehow squeeze in my own custom properties
as well?
