This already revealed some places where implicit conversions were done, including some where its use was nonsense (MouseInput.cpp).
The changes to the Intent class were necessary to keep things working, and this splits things up more neatly.
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).
