[Jonas G. Drange]

use Notifications dbus API to play sounds

* Use org.freedesktop.Notifications dbus API to play sounds by providing a hint (sound-file) to the notification.
* Sounds module export an interface for testability.
* Sound.Present is unused, but since Unity8 won't play notifications forever, the code is kept.
* Notifications module uses sound module to locate and sanity check file paths from apps.

Testing:

1. Save your current notification somewhere. Get it by running this command:
gdbus call -y -d org.freedesktop.Accounts -o /org/freedesktop/Accounts/User32011 -m org.freedesktop.DBus.Properties.Get com.ubuntu.touch.AccountsService.Sound IncomingMessageSound

In my case it was (<'/usr/share/sounds/ubuntu/notifications/Xylo.ogg'>,), so "/usr/share/sounds/ubuntu/notifications/Xylo.ogg"

2. Download an mp3 and copy it to /usr/share/sounds/ubuntu/notifications/<yourfile.mp3>

3. Set the current notification sound to the file from 2:
sudo gdbus call -y -d org.freedesktop.Accounts -o /org/freedesktop/Accounts/User32011 -m org.freedesktop.DBus.Properties.Set com.ubuntu.touch.AccountsService.Sound IncomingMessageSound "<'/usr/share/sounds/ubuntu/notifications/<yourfile.mp3>'>"

4. Test it.

5. Revert the change:
sudo gdbus call -y -d org.freedesktop.Accounts -o /org/freedesktop/Accounts/User32011 -m org.freedesktop.DBus.Properties.Set com.ubuntu.touch.AccountsService.Sound IncomingMessageSound "<'/usr/share/sounds/ubuntu/notifications/Xylo.ogg'>"
