Occult research

Occult research requires the use of a forbidden knowledge center and has its own tab in the research menu. Selecting any occult research will forbid all other research benches and selecting any other research will forbid the forbidden research center.

All occult research is on neolithic level, researching anything occult will make the researcher lose sanity as long as they are researching. Research goes as follows:
 * Decipher strange symbols (50): Basic research required to unlock all other occult research
 * Sculptures (300): Allows you to create sculptures dedicated to each deity, which help with sacrifice
 * Obelisk construction (600): Requires Culptures. Allows you to create obelisks
 * Study succesful cults (3000): Researching this increases the colonist intelectual and social skills, as well cult mindedness. Good research for your preachers.
 * Ritual Attire (300): Allows you to make cultist clothes, which helps with succesful sacrifice.
 * Probe occult deities (100): Allows you to find deities to workship. Repeatable 7 times, until all deities are found.
 * Altar (150): Allows the creation of a basic altar
 * Altar of Sacrifice (250): Allows you to upgrade your altar to tier 2 and allows the sacrifice of meat, plants and meals to gain favor
 * Human Sacrifice (400): Allows you to upgrade your altar to tier 3 and allows the sacrifice of prisoners and the use of spells
 * Chronicling (500): Allows you to read the report of the last human sacrifice at the altar.
