Add time of next realtime contact with ACE

[jeanconn]

Feature request from @richardjedgar

After last week's radiation working group telecon, it occurs to me that one piece of info we might want easily available going into a radiation event is when the next real-time contact with ACE is scheduled to be. Would it be possible to add this to Replan Central page in some easily accessible way?
