Merge lp://qastaging/~3v1n0/unity-2d/fix-multiscreen-indicators-geometries into lp://qastaging/unity-2d

Hi Marco, excellent work! I will test it soon, just looking at the code for now :-)
Meanwhile, a couple of comments:

- Making the Unity2dPanel as implicit parent for the IndicatorsManager can cause confusion. For instance, one could call IndicatorsManager::setParent() and break our assumption. IMHO it's better to have a separate method IndicatorsManager::setPanel(), or a constructor which takes both a Unity2dPanel argument and a parent QObject.

- Member naming: getID() -> id()

- "d->q" = "this" :-)

I've fixed what you mentioned. I used the constructor to define the Unity2dPanel in IndicatosManager.

Thanks Marco! Please bear some more patience: could you change this:

IndicatorsManager(QObject* parent, Unity2dPanel* panel);

to

IndicatorsManager(Unity2dPanel* panel, QObject* parent = 0);

The parent argument is always the last, and can be omitted (in our case it's correct to set it though, so you don't have to change the place where it's instantiated).

Ok, done. I hope it's fine now.

Last nitpicking, I promise :-)
- "Unity2dPanel *panel" -> "Unity2dPanel* panel"
- "QObject* parent = NULL" -> "QObject* parent = 0"

I hope that now it will match all your codying style rules... Sorry, but I'm switching too many projects here :)

Fantastic! Thanks Marco!
