Code review comment for lp://staging/~lemonboy/pantheon-files/update-free-space

The free space now updates on reload (F5). This has to be done manually for local mounts if the free space changes due to pasting or deleting files since this does not trigger a reload for local devices (FileMonitor signals are used to update the view).
While it would be nice to have the freespace indicators automatically update, it can be added in another branch. I will approve this branch.
