Add EON Steel time sync capability

Browse Source 
The EON Steel can use the new 'timesync' interface to set the time
automatically from the computer it is connected to.

This also regularizes the EON Steel command names a bit, and adds a few
new commands (you can also read the time etc, which this doesn't
actually use).
