Previously when the arguments of a function wouldn't fit on a single line, clang-format would put each argument on its own line instead. By enabling the binpack parameter setting, it tried to fit as many on one line as possible instead.

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 colour field in the banner object is also used to store the ride index when a banner is linked to a ride. This commit turns this field into a union with both named fields, to make the code clearer.
It also changes the return types of related functions to uint8 instead of sint32, and makes use of the RIDE_ID_NULL define where applicable.
