Origins of Civilization for 3.7+

Expands the range origins for pre-ftl civilizations:Adds Syncretic Evolution, Post-Apocalyptic, Lost Colony, Calamitous Birth, Scion, Tree of Life, Necrophage, Teachers of the Shroud, and Progenitor Hive as available random origins for primitives (the Mardak Vol are now necrophages). Adds an event where primitives which advance to the Steam Age can then proceed to become Mechanists. Adds events where primitive civilizations or recently-conquered primitive planets can be taken over by Necrophages. Intelligent, natural scientist traits, and materialist ethics now boost pre-ftl progress like they do research speed. This replaces certain random events with similar effects. Primitives entering space on their own have a chance to gain the Under One Rule or Fruitful Partnership origin if they meet the requirements.
