Utopia Park is the only scenario in RCT1 that uses different names in the scenario list and for the park. Since we use the former to identify scenarios, correct it.
Also add an alias to keep the very popular pack by Crappage working.
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).
New command goes by LOADSC in script files and in the enumeration.
Scenarios are stored using the internal also used for localisation.
Scenarios selected can only be scenarios to originally come with one of
the games or expansions.
Modified Scenario Select window to have a mode just for title editor
scenario selection.
