[jdom-interest] insertChild in Element

[David W. Smiley]

I totally agree with what Tom Jenkins said:

	Also, I don't think JDOM should have both getChildren and be the list
itself.  This means there are two ways to do the same thing which I
think should be avoided in an API.  It's not like we have to support
backwards-compatible JDOM clients as JDOM isn't yet v1.0.
