- Renamed the `new` and `realloc` functions to `create` and `resize`
- Added `delete_all`
- Made Mod Data a class:
- Allocation is now limited to prevent out-of-memory crashes: 1024 display lists of max size 2048 and 1024 vertex buffers of max size 4096 per mod
- Added error codes to identify the cause of a failure (name not found, pointer not found, max size exceeded, item pool is full, ...)
