Moved Timeout handling out of 100ms callback: Handling of the timeout is not timecritical and may be done in the main loop. This was needed because writing of flash data shall be done before going to sleep. Having this function in the timer callback would raise the risk of flash inconsitencies due to parallel calls out of the main loop => Created a separate function containing the old timeout detection functionality
