Wordwrap

Hi,

This is my first ever pull request, and first github contribution, so I welcome any criticism or guidance.

I wanted the textbox that I created to keep the width that I set, and to do so, apparently I needed wordwrap to be enabled. It looked like I needed to remove the wrap="none" from the xml.

I added a test, but it appeared to be the only time actual text is put in the xml (other than name, id, h/w, etc). If there's a preference on how you'd like this done, please let me know.

In any case, thanks very much for the library, and I hope you keep working on it!
