Title: Ruby 2.2 Dockerfiles

Based on the 2.1 Dockerfiles, changing only env vars

Tested this locally on my boot2docker VM. I know the `2.2.0-preview2` tag would have to be created in order for the onbuild Dockerfile to work, but I figured I'd throw this up here as proposal before I try to figure out how that tagging process should work...
