Add experimental "show grid users online" console command to show grid users online from a standalone/robust instance.

This is not guaranteed to be accurate since users may be left "online" in certain situations.
For example, if a simulator crashes and they never login/logout again.
To counter this somewhat, only users continuously online for less than 5 days are shown.
