sciter-rs 0.5.58

// Note: there is an issue in Sciter that you can't just call its functions out of nowhere,
// you are supposed to have a main thread.
// Since Rust always spawns a thread per test (it does not matter, to spawn 1 or more threads),
// so we have a problem here.
// If I could create a dedicated "main" thread per test module, that would be fine.
