Revised DebugLog window

Ran into problems with the debuglog window code i posted. Basically, since the log watcher thread is not the form's thread, you can run into deadlock. So i created a fully self-contained floating window, that properly manages the log writing using Invoke(). For more detail on the whole Form thread vs. other threads issue, check out this Code Project article.

Update 6/12/05: Fixed another deadlock issue with the Debug window. See this post for details. The linked source was updated.
