#11 - Added command to backport changelog entries.

We now support a git backport changelog $trainIteration --target $targetTrain,$targetTrain to backport the changelog commit for the given source iteration into the given release trains. If the source iteration is not corresponding to the master branch (i.e. for service iterations), the master branch is becoming an additional target for the port.
