[Qt-qml] "property var" becomes "property variant"

[aaron.kennedy at nokia.com]

Hi,

QML supports declaring object properties with a type "var".  Behind the scenes this actually creates a QVariant property, which behave similarly but not identically to a JavaScript "var".  To reduce confusion, the QML type has been renamed to "variant".  Code that wrote:

Item {
    property var a
}

should now read:

Item {
    property variant a
}

Once this change makes it into the master branch there will be a grace period where both are supported (the "var" case will print a distracting warning of course) of around a week.

Cheers,

Aaron
