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.  
Is there a reason for the space at the end of this label?  It probably doesn't matter, but seems extraneous.
