Add option to restore behavior of using mouse scrollwheel to focus app windows

Honestly, I don't see why middle click should function on inactive launchers by default but not the wheel. But as long as long as it can be turned on somehow I'll be a happy camper.

The use case for this that I think those of us who like it have caught on to without realizing it is that it doesn't require the mouse to come to a complete stop to activate. Actually clicking with a moving mouse of course initiates a drag operation; but with the wheel selection you can just keep right on moving.

I took a stab at this one...

Reverted the AppLauncherIcon to the earlier state that will grab focus if it gets the scroll event, and changed Launcher itself to check its new setting activate_on_scroll to decide if the event should even be sent. New option is exposed at the bottom of the CCSM Unity Launcher tab.

The attachment "lp1288957.patch" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

I've been running on the code pulled from the bzr branch since yesterday and it seems like it's never working after I log out and back in. The box is still checked in CCSM but after I un-check and re-check it's working again. Can anyone confirm? (and/or have I borked my dconf :P)

Hi asmoore82,

Yeah, I think you're right. I'll fix the branch. Thanks for letting me know:)

For those who google this, the quick fix to turn this on in a terminal without CCSM is
[code]dconf write /org/compiz/profiles/unity/plugins/unityshell/scroll-inactive-icons true[/code]

Fix Released in Unity Unity 7.2.0.
