The sound menu should handle keyboard volume/mute keys

[Kazade]

If you open the sound menu, and while it's open press the volume special keys available on some keyboards, the volume doesn't change. The sound menu should handle these key presses and move the volume slider or mute when they are pressed.

The reason for this bug report is I sometimes press play on the sound menu to find the volume too loud, my first instinct is to hit the down volume key on my keyboard but this does nothing while the menu is still open.

Noted Bilal, I tried this feature last cycle but iirc the handover of the media keys from the settings daemon wasn't as straight forward as first anticipated. Marked as triaged as from the user's point of view it's a bug.

This is a limitation of gtk+ (and X): menus grab the keyboard and mouse so that they can close themselves when the user navigates away from them. It's unlikely that this will be fixed before the switch to Mir.
