[ORL] [RK] Added a mechanism to allow addons to set per-slice bindings for specific ring slices: props[idx].psbind can be set to a binding string.
(Custom Rings UI does not support this yet)
[RK] Fixed an issue preventing "only show while present" slice option from adding item slices to rings properly.
[ORL] [ORI] Fixed an error occurring when a slice loop exists in sub-ring slices and the "Nested Rings" indication option is enabled.
[ORL] Fixed an issue preventing the "Bind numeric keys to slices" option from using 7 and 0 keys.
