[QBS] Group's property can not be accessed by qbs

[罗勇刚(Yonggang Luo)]

For example:

Group {

    name: "source of " + namespace

    prefix: namespace + "/"

    qbs.install: project.installApiHeaders

    qbs.installDir: headerInstallPrefix + group.namespace //TODO:Fixme
this.namespace is not works

}

The qbs.install can access Project's project.installApiHeaders
but qbs.install can not access Group's  group.namespace
