Merge lp://qastaging/~fboucault/unity-2d/multiline into lp://qastaging/unity-2d/3.0

There is a few things to take into account:
- this is a workaround for a missing feature in the Text QML element
- the Qt developers implemented the feature properly in a more recent Qt version: http://bugreports.qt.nokia.com/browse/QTBUG-12305 but the patch to Qt is quite intrusive and not trivial to backport to 4.7.2
- this workaround has a big, acceptable drawback: ellipsis never happens (the ... are never displayed)

Also it is a known issue that when hovering a result that has its label cut will expand the text over the rectangle that indicates the selection. It is not very pretty and we will devise a solution for that later.

When I open the home page of the dash, I get 8 times the following warning:

unity-2d-places: [WARNING] file:///…/places/TextMultiLine.qml:28: ReferenceError: Can't find variable: mouse

That looks quite ugly indeed. Wouldn’t it be better, as a temporary measure, to never expand the label? The text would always remain cut beyond the first two lines, but that hopefully doesn’t affect usability much (tested in French, most applications’ names don’t go beyond two lines of text).

Another solution is to fix the selection rectangle so that it outlines only the icon, excluding the text, like it does in unity.

Agreed, let's do that separately.

I'd like to keep that way for other reasons such as making it a bug fix for next week rather than an added feature (expanding on hover).

Fixed. Very sorry about that.

Ok, then it’s good to go!
