The command line gives the name of the scenery lowercased, and the sceneries made on Windows name their files and includes in any case: on a case-sensitive filesystem they weren't found. FileCased() finds the file whose name differs only in case; the parser and the scenario loader use it. A scenario that can't be opened logs the reason and goes back to the launcher instead of ending with an exception.
