Title: Change cap3 skeleton Gemfile to use rbenv from github.

capistrano-rbenv on rubygems is actually another gem for managing rubies: http://rubygems.org/gems/capistrano-rbenv

from here: https://github.com/yyuu/capistrano-rbenv

so I think you actually meant to use this one: https://github.com/capistrano/rbenv
