Work on NEWSOURCE-17

Items that are already in UE or ISWG sources are commented out to remove duplicate definitions. Several equipmods that are in this source should allow the item to become a container, but that is not possible with the current data model. TODO comments are left in the LSTs but these are not coded. There are a few misc items left to add.

Heirloom Weapon trait is still an issue. "Heirloom Weapon: You carry a non-masterwork simple or martial weapon that has been passed down from generation to generation in your family (pay the standard gp cost for the weapon). When you select this trait, choose one of the following benefits: proficiency with that specific weapon, a +1 trait bonus on attacks of opportunity with that specific weapon, or a +2 trait bonus on one kind of combat maneuver when using that specific weapon." I don't know who to implement this.
