Cannot override certain key combinations involving Super

[Paul Gear]

When defining keyboard shortcuts in System Settings -> Keyboard -> Shortcuts, several combinations are never honoured. These include setting:
- Launchers -> Launch calculator to Super+C (launches search photos instead)
- Launchers -> Launch email client to Super+M (launches search music instead)
- Launchers -> Launch terminal to Super+T (launches Rubbish bin instead)
- Launchers -> Launch web browser to Super+F (launches search files & folders instead)
- Launchers -> Search to Super+S (launches Workspace Switcher)
- Navigation -> Switch to workspace # to Super+# (launches the corresponding launcher icon instead)

It is non-obvious that this shortcut change has not been honoured, and there is no list of keys to which this applies.

This is somewhat problematic. As compiz gets the events, checks if it uses that shortcut. If it does then it eats the event and its done. If it doesn't eat the event it gets sent to gnome control center (now unity control center i think?). Which then gets to the right shortcut.

So the only way to get this to work correctly, is to go in ccsm (compizconfig setting manager) and change the shortcut in unity plugin to not open photos scope when you press Super+C.
