[window management] unity8 and 3 finger window drag

@mpt please confirm design recommendation with Ben and John, thanks

In the draft Mir spec I did specify some shell-independent protection against bug 1438465. <https://goo.gl/9zrWsY> (Canonical-only link, sorry)

That does not mean, though, that I'm involved in the design of Unity 8 at all. So I think this is assigned to the wrong person.

3-finger gestures should be enabled in Unity8. Design is in progress at the moment but my feeling is that 3-finger drag in windowed mode would be used for moving windows around. And in staged mode 3-finger drag could be used for moving apps between stages (main stage and side stage). This functionality will be confirmed once the spec is ready and approved.

This bug was fixed in the package unity8 - 8.12+16.10.20160617-0ubuntu1
