[suggestion] selectable cost profiles

[morris2009]

It would be very nice to have different cost profile options to display the cost of printed part.
In my case, as example, when I print something for family & friends the cost estimation is just fine as it is now, all costs included like the printer costs.
But if I print something for myself, i would love to be able to 'unselect' the operating costs and just see the costs for printing the part.

I already have the printer, use it for printing for f&f and in those external costs it makes sense that operation costs are in there, but for the incidental prints I do for myself on this printer it would be nice to see material/power costs only.
