lllucius 1fab1cdb21 Bug 337 - New logger class allows log to be initialized immediately without crashing Mac empty project windows
This is an older one...originally from 2011.  Bug says it all, but basically it allows logging
to begin immediately upon startup for all platforms.  And it has multithreading protection, so
it should now be safe to log from the non-GUI threads.
