And reordered all the source files in the projects according to name sort. And removed all the deleted files, including some which were forgotten in previous updates, but left as 0 byte files. Finally, updated the project to use C23 / C++23 language standards. Signed-off-by: Christopher Snowhill <kode54@gmail.com>
