This version brings bug fixes for performance and caching.
Also looks like 2.0.x won't be supported anymore and could be a good idea bump version also in 3-1-stable.
Upgrade Sprockets to 2.1.0

@jonleighton (release manager :P) what do you think about bump Sprockets to 2.1.0 in Rails 3.1.2?
It looks like there aren't big changes from sprockets 2.0 to 2.1, so I think it should be ok to put in 3-1-stable. Do you want to do a pull request? (with CHANGELOG entry please)
