v0.17.1: The perk shop, repriced

The shop had a cliff in it. Most perks maxed out quickly, three were priced past anything a person would actually play toward, and a few of the strongest were almost free.

Changed

• Synergy Schematics, Starting Level and Aegis are far cheaper. Their final ranks used to cost close to a whole prestige, so nobody was ever going to buy them over the extra cannon. They now top out at around a quarter of that, and sit alongside Weapon Slots and Reinforced Array as the premium end of the shop rather than past it.
• Weapon Slots, Draft Choices, Targeting Computer and Deployment Network cost more. Two more weapons, an extra card every draft and full predictive aim are among the biggest swings in the game, and all of them finished inside three runs.
• Everything else is untouched.

Perks you already own are unaffected, and nothing here changes how a run plays.
