Various fixes to Chromeframe and a fix to bolded elements

Fixed the click event not hiding the frame and did some minor styling changes.  I commented out 2 lines that I thought were unnecessary but left them in if you want to keep them.  The box shadow isn't going to show up in <IE9 which is when the frame pops up.  Also the white text shadow when the background was white didn't really make sense to me.

Also the 'strong' and 'b' tags weren't properly bolding elements because they were inheriting their font weight from header_weight.
