[jdom-interest] Modified XMLOutputter which optionally omits white space

I think my changes address the problem of manually created elts or elts
moved
having inconsistent indentation.  If I use my new constructor:

XMLOutputter("    ",true,true);

I have asked XMLOutputter to properly indent the output adding spacing and
newlines where it wants and also to remove the old, probably incorrect,
formatting (my new code).

In my limited testing it appears to do the right thing.

I'm happy with a larger, better solution, but this one appears to be small
and slightly better for now.

Brad
