equip stuff
Implementing equip, fixed equip bugs
Menu Equip/Unequip selection steps
EquipSlots Interface
include set
Equip refactor, UI, still unfinished

A lot of things are still baked in the code (e.g. assuming you're only
equipping to right held). Still a lot of work to be done
Removed debug messages
Equipment additions - broken
EquipGroups finished!

Any item will holdable (not yet!). You can only access it's
"equipActions" (e.g. shoot gun) if it is equipped in the slots its
EquipGroups define. Example: You can pick up a rifle with your right
hand, but not shoot it. In order to shoot it you must equip it to both
hands (RightHeld and LeftHeld), where you'll gain access to "Fire".
