Merge lp:~paulliu/unity/add_superkey_configuration_dialog into lp:unity

[Ying-Chun Liu]

Add a configuration dialog when super key is disabled by OEM.
The window will be shown each time when the dash button is pressed first time and the super key is disabled.

[Neil J. Patel (njpatel)]

Obviously this won't apply to Unity trunk anymore, but I don't mind if you want to merge it into the 0.2 series if it will lessen the distropatch burden for OEM.
