Issue #1345246 by stopshinal, mrfelton, katbailey, beansboxchrispang: The widget does not support the term query type

I left behind the +/- simbols for the collapsible blocks. I have been working with Bartik theme as default and I noticed that blocks don't have class any class in their titles but instead use a simple h2 tag; I have updated the selectors to consider these h2 as tag however since there is not more html tags inside them the sprite used for the +/- icon doesn't work well.

updated styles accordingly
