* When building with CMake, dynamic model lists are now generated
* Factored common code out of generate_*_list.js files to deduplicate
* Better separated generated model lists from main game code
`dynamic_asset_data.c` and `dynamic_animated_asset_data.c`
previously #included the corresponding generated headers, and
`dynamic_asset_loader.c` declared externs for the contents.
This messiness was likely done so the generated code would be built
automatically (the Makefile globs all C files under `src/`).
Now, model list data is output to C source files which are built
explicitly. This, with some refactoring, allows the previously
mentioned source files and externs to be removed.
This is a bit hacky in the Makefile but will be automatic under
CMake by using target properties.
* Reorganized some files under `tools/`
Incidental changes along the way:
* Move `export_level.lua` to `tools/level_scripts/`
* Small reorganizations/fixes to existing `CMakeLists.txt` files
* Support passing absolute paths to level export
Some parts need to be cleaned up/removed/streamlined after the CMake
build can build the game on its own and compatibility with what the
old makefile does is no longer needed.
