FR: Choose whether the generated vias should be covered by the solder mask or not.

[boromyr]

If the generated vias are used for thermal dissipation, you may not want them covered by the solder mask when you have selected "Covered Vias" by default in the board settings

This could be a rough solution that adds an opening on the welding mask in the two layers F and B, a new checkbox could make the functionality selectable:
