Moved internally used functions (hint_node -> hint_node.internal).

Changed how we check whether the node graph needs to be rebuilt.

Changed to ignore hints for nodes with IDs greater than the number of nodes included in the .ain file.

Fixed an issue where applying a hint to a large ID like 8191 would return a NULL Entity and not work properly.

Maximum number of nodes changed from 4096 to 8192.

Changed to not force "ai_norebuildgraph 1".

Changed to force "ai_norebuildgraph 1" if enabled.

Added support for loading hints from data/map_hints or data_static/map_hints folders.

search order is
data/map_hints/<map_name>.json
data_static/map_hints/<map_name>.json
maps/graphs/<map_name>.hint.json
