Fix engine bug message when a textbox contained an OOB hero ID. reporterr can now be called outside of a script

(Happens in the 1997 Wandering Hamster demo)

reporterr now acts mostly like scripterr, in that it hides error messages
in-game in release mode (whether inside the interpreter or not), and otherwise
it translates the script error level to a debugc errorlevel and shows or logs
the error, as suitable.
