Line breaking using word-wrap: break-word.

Use css word-wrap: break-word to break long words.  Also set overflow: wrap as this is a revision to the css that takes over the word-wrap functionality.  This is set on the body tag to get everything.

Removed the breakHtml_ifwhitefix calls in Data.pm as we no longer need this. Also removed the domain shortening when adding the domain at the end of urls.

word-wrap does not work in a filedset properly, so set the edit templates not to put the previews in a fieldset so that everything should work properly.  This required the previw_comm template to be slightly changes so that the bottom border could be put on the preview for the comment.
