More IE friendly diff output related templates.
I thought i could use CSS to render properly the diff blocks in IE.
But i was obviously too optmistic and didn't realized that IE only
renders preformated text for pre tag content...
So i had to rollback some of my changes to accomodate to this IE
bug/limitation. A diff blocks become pre tags, and diff lines
become span again. Hopefully, the pages continue validating.
