Show progress during fixing

Show simple progress during fixing - for very big projects, to prevent killing process on "no output for so long time...".

* now show stopwatch times on verbosity debug level (no very verbose)
* add Events (for not mixing responsibility of classes)
* show progress as '.' or 'F' per file (on very verbose verbosity level)
