Remove popup console logger and use log4net. Add verbose logging setting. Logs to rolling file by default, 1MB, 2 files, 2MB total.

#1: Support forced grouping. Add support for multiple match rules. Backwards compat maintained (if no Rule then Name is used like before).

Improvements: - now enumerates all windows for a given process - only processes windows that are visible and have a main parent with a title (this seems to be the best of all worlds) - added a bunch of native win32 api methods
