Support of any blade base shape

[RaulBejarano]

Right now the only available blade base shape is a circle or elipse (by resizing the circle).But it will be awesome if any kind of blade base shape can be set. So....:

AS designer
I WANT to use any kind of blade base shape
SO THAT I can create more customizable propellers

Thougts on this: I think this can be achieved using children, so maybe it will be posible transform this module into an operator. But it can be difficult to manage the blade thickness.
