PCBnew: Unable to modify Gerber Job/Material Stack Up

Bug Description

When plotting a design from within PCBnew, it is possible to generate a Gerber job file. This file is very useful in aiding communicating basic information to the board house.

This text file includes, among other things, Material Stack Up.

However, this stack up information is incomplete and not editable from within PCBnew.

In particular;

1A) It is not possible to edit the laminate dielectric material itself (the default is FR4, but I can't seem to change it) or copper weight for each layer.

1B) It is also not possible to specify Copper weight, layer thickness, material thickness, or Dk/Df values.

2A) The material stack up is incomplete; though it appears to provide for the laminate material, it does not provide a mechanism to specify the soldermask (and its colour), or the pre-preg (and its weave/rosin density)

2B) NB: It is definitely possible to have multiple layers of pre-preg between laminate layers, and it would be very nice to have the ability to specify this.

Ideally, I would like to be able to to fully specify a nominal stack stack up consisting of;

Soldermask (name, thickness, colour)
Copper (thickness and finish (Direct Immersion Ag, ENIG, etc)
Pre-preg 1 (Material, Weave, Rosin)
Pre-preg 2 (Material, Weave, Rosin)
Copper (thickness)
Laminate 1
Copper (thickness)
Prepreg 3
Prepreg 4
Soldermask (name, thickness, colour)
