Merge lp:~3v1n0/unity/expo-dnd-removal into lp:unity

[Marco Trevisan (Treviño)]

ExpoLauncherIcon: Set the viewport size to 1,1 (i.e. diable workspaces) on icon Removal

Like when dragged to trash!

This is the last part of the so awaited saga "Launcher - Workspace switcher should not be in the Launcher by default".

Now dragging the WS icon to the trash, disables the workspaces.

It requires the compiz fix lp:~3v1n0/compiz/ccp-core-options-save-fix/+merge/147716 in order to work after a compiz reboot (i.e. to actually save the setting)

Tests added.
