Implemented basic stub for file logging

* rust-launcher/src/log_helper.rs: extracted log_impl from os.Implemented (always on for now) call to log to file
* rust-launcher/src/main.rs: made aware of new log_hlper module
* rust-launcher/src/os_access.rs: adapted to log_helper. Added forgotten is_verbose to windows os impl.
