Bug 12863 - News in OPAC: HTML broken with nested p tags and multiple thead in same table

This patch fixes broken HTML in OPAC news by replacing table display
with divs.

To test:

Create multiple news for OPAC
Validate with HTML validator or check source code
Result:
Error with nested p tags
Table header thead is repeated for every news (not allowed)
Bonus testing: Let a screen reader like NVDA read the news and try to
understand it with closed eyes.

Apply patch
Result:
No more HTML errors in news
Screen reader reads news properly

To style you can use classes newscontainer, newsitem, newsheader,
newsbody and newsfooter.
