The filesytem stuff actually does something now

The code is still messy but for now, I shall focus on laundry (and after that, sleep)

Once the user enters the filename, this now dumps the entire contents of the
file to the screen.  It would be nice to have this wait for the user to push
enter or something, not sure how possible that is though...
