New fix for [#29940] Stretch To constraint breaks scaling in Transform constraint, previous one caused bug [#29962] linked objects not correct on r4361, should be fixed now.
Org code was working with isotropic scaling, but when scaling only one axis, it was broken. First fix just disabled completly scale handling. This version only takes into account scaling along local Y axis, as this is the only one affecting that constraint!
Sorry for the mistake, hope this time it will be ok.
