Pilot SPA costing PVs

[Korsriddare]

Noticed that when trying to add SPAs to units, the listed points are translated into PV when they are just supposed to be SPA cost (e.g. skill 3 pilot can have up to 2 SPAs with total SPA cost of 4), and should not cost any PVs.

Reference from the official rules forums when someone had a question on this:
