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).
Before adding a name to the clipboard buffer, it checks for spaces at
the end of the name, to prevent copying those.
It also moves some logic from the "mouseup" function, and moved memory
deallocation within the same function where it got allocated.
