[QBS] Properties item are broken in qbs 1.2

[Aleksey Sidorov]

Qbs from QtCreator 3.1RC falls in this code:

import qbs 1.0

Project {
    property string binPath: "/usr/bin"
    property string libPath: "/usr/lib"

    Properties {
        condition: qbs.targetOS.contains("osx")
        binPath: "/Users/boo"
        libPath: "/Libraries/foo"
    }
}

Also on this code snippet

import qbs 1.0
import qbs.FileInfo

Product {
    property string bisonPath: "bison" //TODO rewrite on binary probe
    property string flexPath: "flex"

    Properties {
        condition: qbs.targetOS.contains("osx")
        bisonPath: "/usr/local/bin/bison"
        flexPath: "/usr/local/bin/flex"
    }
}

QtCreator displays an error:  ReferenceError: Can't find variable: qbs

In the qbs 1.1 these problems were not observed.
