 * Global entrypoint for both the FML part of the relaunched (live) and the relaunching (relaunch) runs. Execution
 * begins during static initialization to be as early as possible. There aren't any security implications, but especially
 * on Windows it can be problematic if two processes try to open up the same file, so we try to avoid these conflicts.
 * Also, it's just a faster launch.
