I went over the commits ab7f22f..8726712 (bulk format commits for game actions to management inclusive) and corrected all mistakes I found. Most of them have to do with arrays missing trailing commas, making clang-format indent the entire array or not add breaks between the values.
Clang-format sees the text behind `#pragma region` as code and formats it. Instead of stating the copyright and date there, it's now in the comment block right below it. The text "Copyright" is left in the `#pragma region` line, as clang-format sees it as a single identifier.
I took the opportunity to normalize the dates, and add the copyright notice to the source files where it was missing them (except for third-party and the generated resources.h file).
