already omitted flag for triggered functions after omit+keep_evaluating

Given the caveats noted in http://www.gammon.com.au/forum/bbshowpost.php?bbsubject_id=12533
("Providing the other trigger(s) haven't added to the output buffer..." and "My reply may not work for long lines...")

Maybe a 5th parameter could be added to trigger function calls after name,line,wildcards,styles that denotes whether the matched line has already been omitted? Or maybe a GetInfo flag that resets at the start of every triggering round and toggles if any trigger omits from output?

What would you define as omitted? For example in ProcessPreviousLine.cpp line 462:



That's omitted by a plugin callback (OnPluginLineReceived), not a trigger match.

OK, I've changed the output line management thus:

Previously a local variable was used to detect if the line was (about to be) omitted from output. Now it is a global variable which you can test with GetInfo (124).
