sc2: war council ascendant, arbiter, skylord

[MatthewMarinets]

• Ascendant -- Ability Efficiency. Nerfed, abilities cost +25 energy, upgrade restores their costs (25, 75 -> 100, 50)
• Arbiter -- Ability Efficiency. Nerfed, abilities cost brood war amounts, upgrade restores costs (150, 150 -> 100, 50)
• Skylord -- Hyperjump. The upgrade just unlocks Hyperjump (renamed from Tactical Jump because the data name sounded cooler and more Tal'darim)

Also touched up the Skylord actor data a little, in particular giving them that warping-in effect when they're built from the stargate (spotted this on the void ray, easy to add), and touching up the hyperjump actors a little to use the warping in models/anims.

Progress on #152

Also updating Arbiter Spacetime Anchor to provide an alternate stasis rather than modifying the existing one. Otherwise, the upgrade is often a nerf.

Reordering the Arbiter command-card per discord request, to put long stasis close to stasis while maintaining the vanilla button positions
