Implemented writeZ parameter on render.draw3DLine (thegrb93#1611)

* initial implementation of writeZ on draw3DLine

* oops

* restored default values

* parameter note

* requested PR change

* removed unnecessary typecheck

* implemented writeZ on draw3DWireframeSphere

* implemented writeZ in draw3DWireframeBox

* set default behavior to true
