Release 2.10 bugfixes

This is a bugfixing branch for 2.10.  I'm putting it up here for review, but its not going to sit for a long time.  I will pull it myself in a few days or so.  

-  I added aria labels to radio buttons, selects and checkbox answer types.  
For various reasons (mostly because there might be "problem x" in front of "answer x" but not necessarily) when I set up the aria-labels the assumption is there is always a space at the end in case there needs to be something appended.  I could probably leave the space off of this one because its unlikely anything will come after option, but you never know.
