Add prependChild feature

[angerthosenear]

Following up with previous feature request, would it be possible to prepend a Child element? I'm currently using my string replacement method to do this.

I know prepending a Child is a rarely used feature, but I would greatly appreciate it.

Thanks again,

Ended up changing some of my code around, so you can skip on doing this if you want since it would be so rarely used.

As you said, I also find this very rarely used feature, so I would rather skip implementing that.
