Title: Document that we support Ruby 2.1.

There were two places we didn't specify that we supported 2.1. I chose 2.1._x_ because 2.1 versions are coming out rapidly enough that I didn't want to hard-code 2.1.5 and then have to fix it later. Let me know if you'd prefer just "2.1" or something else entirely.
