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).
The game tries to use a ui context while setting up a platform environment. Let the platform environment be created before looking for the RCT2 directory. This is a bit hacky at the moment, but a necessary fix until it can be cleaned up.
