Updates Goshen to functionality for CK2's 3.0 patch. It also brings Slavery to Goshen in three Forms; Indenture, Thralldom, and Chattel.
This form is individual, a slave being servant to a master for a set time then eventually released.
This is the first form of population slavery, where groups of people are enslaved for hard labor, though children born in Thralldom are freeborn.
This is the pinnacle form of population slavery, with it children born to slaves are themselves slaves.
Thrall and Chattel forms enable the Slave Raid cb so they can fill slave holds in their capital as well as 'honorably' gain court slaves. This is the only way for Thrall slaveholds to fill.
With slavery comes anti-slavery, realms averse to slavery can use the Anti Slavery cb to lower a Slave realm's laws every 20 years.
