[scala-bts] #3094: xml scope not handled when copying elements

here's a scala session:

scala> val x1 =
x1: scala.xml.Elem =

scala> x1.child(0).namespace
res0: String = http://www.example.org/scope

scala> val c =
c: scala.xml.Elem =

scala> val x2 = x1.copy(child=c)
x2: scala.xml.Elem =

scala> x2.child(0).namespace
res1: String = null

scala> :quit

I think that if 'copy' is passed the 'child' parameter, it should use a
copy of that child where the scope is a merge of that child's scope and
it's own.
