Better Questing - Multiblock and Structure Integration

Quest authors can attach a task to a Recurrent Complex multiblock, so completing the quest requires finding or building that structure. The mod adds a Locate Structure option that directs a player to the chosen structure, and a getStructureName function that reports the structure at the player's current location. Each structure task is defined in a data file with its dimensions and the target block that must be present.

The mod keeps its own data files to track which Recurrent Complex structures exist in a world, so quests can refer to them reliably. It needs to be present during world generation, which means structures are only added to worlds generated after the mod was installed; existing worlds gain them only for chunks generated later. It is published for Forge 1.12.2 only, with the 1.0.9 file dated 2023-03-21, and it runs on client and server, so the server and every player need it. It is open source under the MIT License.
