Code review comment for lp:~didrocks/unity/fix-lens-shortcuts

I've made the change mentionned by Tim in UnityCore, I've also fixed another one in UnityCore which had a similar pattern.

The "quick typing shortcut" is now fixed as well. But that makes me thing that we should have a keybinding controller which has a reference to both models to trigger the actions in both the Launcher and Dash, being able to know about both part and so avoiding the "show/hide" in a short period of time like we had there.
I initially put everything in the Launcher as it's where we controlled all the Super keys, but it's not the case anymore with this branch, so we should think about it. I'll get to it, but maybe after this release.

Please tell me if it fixes this :)
There is still the issue in first launch (will need to check compiz registration process with Sam)
The numbers not showing and acting is an oneiric regression, indeed, not related to this branch. I'll try to have a look there as well later (some people will apparently break some libunity ABI, and that + patch piloting + zomg new Qt! needs some attention from now ;))
