Next commits will do some refactoring and then implement the logic to handle these changes

* refactored startup classes

* initial base level logic for file watcher

So this is very basic first level of file watcher service that watches the file and then also takes care that the file is wasnt changes since last startup. Initial changes only take that the file last modified is verified and just any change in file simply will give you a message box telling that something changed. More advanced and robust checks in upcoming commits

* missing copyright added
