Omit less-useful statistics for non-admins (#906)
Omit less-useful statistics for non-admins (#906)

Some of the new project_stats are probably less useful right now,
so only bother showing them to admins.   This makes loading
project_stats faster for typical users and guests.
The data is made available to the public via JSON,
so no data is lost & anyone can recreate these graphics if they want to.
