These three patches fix the not highlighted active filter in the advanced,
jeckyll and DownLoard themes.
The jeckyll theme patch requires the button_sel.png file in
videodb/templates/jeckyll/images/. Not sure if it's a good color or even the
intended way to do this, but it works..
The DownLoard theme patch isn't done very well because I used spaces to indent
all the filters, but it looks fine for me.
