[jdom-interest] Still to do - Text 'merger'

Hi all.

I have moved this code in as the new method Element.simplifyText().


It is a non-recursive method. I think the name is better than 'merge', 
'join', or 'normalize'.

I think the recursive means of doing it is easy enough to code 
(three-liner), so it does not add much value.

I think it has enough value to be included.

Unless someone can come up with better names, options, I think it will stay.
