Rename Reporting#println -> Reporting#echo

There's a trap otherwise that, when in a class inheriting
from Context (and with it Reporting) a call to println will
go to this.println and therefore might not print at all, if
the current context buffers messages. I lost a lot of time
on this on several occasions when I scratched my head why
a simple debug println would not show. Better avoid this in
the future for myself and others.
