DA Simple Dynamic Lighting

Improved offhand compatibility and functionality:

• Double-tap Sneak to swap hotbar-selected items with offhand items for offhand-eligible items. For example, if you have a shield in your offhand and torches selected in your hotbar, double-tap Sneak will exchange these items. This also works if offhand or hotbar selection is empty! A brief delay is used to prevent accidental swapping, so it won't swap when climbing, flying or blocking.

The next update to this addon will enable the ever-elusive offhand-item placement (giving time for Mojang to work on some of the backend functionality to ensure this works consistently every time).
