Craftable NPC Spawners

This mod fills a niche that I felt could have been further expanded upon. It adds expensive recipes to craft NPC Merchant spawners to Tier 3 (in other words, Gamma sector and beyond, to be clear). They're craftable at a Metalworks Station, and all of them cost 4000 pixels and 20 titanium bars.

In addition to the standard NPC Merchant spawners, I've also added an Avian Airship Quartermaster (aka Gun seller) Spawner to the game, which is craftable like all the other merchant spawners. Note that because of the way it's coded, spawning one on a ship, regardless of the ship's position, will result in a tier 1 gun shop. It's best used on a planet of the tier you want, rather than on the ship, as otherwise the guns' damage will be absolutely pathetic for Tier 3 and up.

Changelog: 1. 2: Accidentally named the recipes directory "recipies". No wonder it didn't work. Fixed now. 1. 1: Updated to Angry Koala and switched to the merging system for player.config for better compatibility. 1. 0: Initial version for Offended Koala.
