Request Filters UI Issues

There are two minor issues with the Request Filters feature found in Host > Host Settings > Other Settings (tab).
First, when you enable request filters and then choose to create a rule, the icons for Save and Delete are massive in specified size when the images themselves are actually quite small.  (see http://screencast.com/t/8jrG8T73w1&nbsp
Second, the link to the MSDN Server Variables reference is not an active URL anymore.  This one should replace it.
