Skill requirements on doors / duplicant checkpoint

[Raukgorth]

Please add a new building or modify existing door / building (duplicant checkpoint) so we could set minimum skills requirements to enter an area.

For example:

Atmosuit dock could have a agility requirement setting, so dupes with negative agility could not go in areas where an atmosuit is required.

Doors to industrial area could have Machinery skill requirements

Farms could have Farming skill and so on.
