Reduce the height of the feedback page.

Reduce the height of the feedback page.
The current height of the feedback page is causing the bottom of the page to get pushed off the boundary on certain screen sizes. The problem is now worse on other platforms due to the System Information link also being available there. Decrease some of the unnecessary padding on the feedback page to make sure it fits on the screens of machines with smaller displays.
