Discoverable areas (Patreon)

Finally got some code done that had been on my list for quite some time, dynamically "discover-able" areas. So that when you arrive in a new place, you will discover adjacent places. There are some bugs, but it works for the most part. The reason this was much more difficult than expected, was because we're doing communication between two very different plugins, the Overworld and the new Render engine. The engine that allows the clouds, and a whole lot more in the future.

But in the end, it gives us the power to make for some very neat scenarios, events that happen when you arrive in a certain spot, and soon paths that unlock with quests.
