Add timestamp to startup.txt

[Iritscen]

The Daodan's initialization messages in startup.txt should include a time and date. One benefit is that we will be able to tell when Oni was launched in relation to the timestamps in the AEI log files (for instance, did the user forget to launch Oni after running the AEI?).
