Bug 32006: Add page-section for local use system preferences

To test:
1. Go to the System preferences > Local use
2. Notice there is no page section and the table has much more space on the left than other system preference sections
3. Apply patch
4. Look again, the extra space on the left should be eliminated and the page-section should be added.
5. Use an HTML validator to spot errors.

Note: I elimiated the inline style on the table that set the width to 80%. I don't see why that is needed but if it is we should be using CSS to do so.
