milestone cost in getHubTerminal

[derpierre65]

it would be nice to add the hub milestone required items and the progress (with the current item count or the %) like in getSpaceElevator, example:

{
  "MilestoneCost": [
    {
      "Name": "Assembly Director System",
      "ClassName": "Desc_SpaceElevatorPart_7_C",
      "Amount": 500,
      "Progress": 250
    }
  ]
}

or maybe add the Inventory like in the space elevator

Notes for later: AFGSchematicManager ->mActiveSchematic may be of use for this
