Small addition

Added a stripped down rules reference; it has the basic mechanical effects for interacting with the different parts of a hearth and for making use of the various Boons, as well as the new moves.

There's also now a document of sample spells; this is just the list from the end of the original Witchery document with no mechanics attached.  It's being provided for purposes of inspiration while using Witchery for the Ironsworn: Starforged System.
