Comment 1 for bug 274965

Fixed: Filebrowser example doesn't show files on N95
- Exception catching was around the loop, which lists the folder contents. If there was at least 1 entry, which is protected from os.stat(like sys or private), the whole operation failed and empty list was returned.
- Tested on emulator only( turn on capability checks )

Fixed: filebrowser does not close by selecting exit.
- added appuifw.app.set_exit()
