Added a QFileDialog to let the user select a path. Before, the path
was statically assigned with "../../" , which is not optimal.
I also modified the findFiles function to check for text files in
general and not only *.cpp and *.h files. Lastly the result of the
word counting is now displayed on the console, as I think this is an
informative output from this example.
