Folia support

Servers

• Dialog Engine now runs on Folia as well as Spigot and Paper, still one jar. Clicks, actions, [delay] and page turns run on the player's own region; [console] actions run on the global region, and a failed one still stops the actions after it. Opening a dialog for a player in another region, from the console or from another player, works too.

Drawn dialogs

• Fixed: a Studio dialog with a sorted box showed empty slots. It is now sorted as RP Engine sorts it.
• Fixed: a "Show when" condition with an unclosed bracket, or two values with nothing between them, counted as true and showed the piece. It now hides it, as Studio's preview does. A choice can also use * for any value that is not empty.
